There’s a specific, sinking feeling that every bike or motorcycle owner knows. It’s that moment of hesitation when you’re about to walk away from your prized possession, leaving it chained to a public rack or a pole. You do a quick mental calculation: Is the lock strong enough? Is the area safe enough? Will it be here when I get back? For years, I relied on flimsy cable locks, telling myself they were “good enough.” That illusion was shattered when a friend’s expensive e-bike vanished from a “secure” garage, the snipped cable lock lying on the ground like a sad, metallic noodle. That incident was a wake-up call. It taught me that casual security is no security at all. In today’s world, a deterrent needs to be visually imposing and physically formidable. This is the exact problem the yarlung 2 Feet Security Chain Heavy Duty aims to solve—it’s not just a lock chain; it’s a clear, heavy-duty statement that says, “move on to an easier target.”
- Yarlung heavy duty steel security chain 2 feet long, link thickness 3/8", inside 5/8"W x 1 1/2"H. Ideal size suited for the purpose of securing the bike and other possessions.
- Made of hardened steel zinc coating, anti-rust, anti-corrosion, our security chain is resistant to sawing and the welded finish makes prying insurmountable.
- Features a nylon sleeve to protect your property from scratches and damages at the time of using it. The users do not face any kinds of troubles meanwhile offering great security.
What to Consider Before Buying a Heavy-Duty Security Chain
A Bike Chain Locks is more than just an item; it’s a key solution for peace of mind. It’s the physical barrier between your valuable asset—be it a motorcycle, an electric bike, a trailer, or a commercial gate—and a potential thief. The main benefit of a heavy-duty chain, as opposed to a cable or a U-lock, is its combination of intimidating strength and flexibility. It can be wrapped around awkwardly shaped objects and secured to a variety of anchor points. However, this strength comes with weight and, in some cases, a lack of portability. Choosing the right one means balancing the level of security you need with the practicality of using it day in and day out.
The ideal customer for this type of product is someone facing a high-risk security situation. This includes urban commuters parking their e-bikes on the street, motorcycle owners needing overnight protection, and property managers securing gates or expensive equipment like generators and welders. It’s for the user who prioritizes raw, uncompromising strength over portability and convenience. Conversely, this might not be suitable for those who need a lightweight, quick-use lock for a low-risk suburban coffee run. A casual cyclist might find the weight cumbersome, and someone needing to lock two bikes together would find a short, heavy chain impractical. For them, a longer, lighter chain or a simple U-lock might be a better fit.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The length of the chain is paramount. A 2-foot chain is extremely secure because it leaves no slack for a thief to use leverage tools, but it severely limits what you can lock to. Before buying, physically measure the distance around your bike’s frame, wheel, and your most common anchor point (bike rack, pole, ground anchor). Also, consider the inner dimensions of the links to ensure your chosen padlock’s shackle will fit through them easily.
- Capacity/Performance: The performance of a security chain is measured by its resistance to attack. Look for the link thickness—anything 3/8″ (around 10mm) or more is considered heavy-duty and resistant to most hand-operated bolt cutters. The shape of the links also matters; square or hexagonal links are significantly harder for cutting tools to grip than traditional round links, making them a superior choice for high-security applications.
- Materials & Durability: The material is the heart of the chain. “Hardened steel” is the key phrase to look for. This process heat-treats the metal, making it incredibly tough and resistant to sawing and cutting. A quality chain will also have a protective coating, like a zinc finish, to prevent rust and corrosion from exposure to the elements. A fabric sleeve is not just for looks; it’s essential for protecting the paint on your bike or gate from being scratched by the heavy metal links.
- Ease of Use & Maintenance: Heavy-duty chains are, by nature, heavy. Consider the weight (1.41 kg or over 3 lbs for this 2-foot model) and how you plan to transport it. Maintenance is minimal but important; periodically check the protective sleeve for tears and ensure the chain itself remains free of rust, especially if the zinc coating gets compromised. Remember that most high-security chains do not include a lock, so you must factor in the cost and selection of a compatible high-quality padlock.

First Impressions: A Short, Stout Beast of a Chain
The moment the package containing the yarlung 2 Feet Security Chain Heavy Duty arrived, I knew it was different. The sheer density was immediately apparent. This isn’t your hardware store variety chain; at over 3 pounds for just two feet of length, it feels substantial and serious. Unboxing it revealed a thick, tightly woven nylon sleeve covering the entire length, which one user aptly compared to the durable sleeves on winch lines. It feels rugged and capable of withstanding significant abrasion. Peeking inside, the links themselves are impressive. They are thick, square-cut pieces of hardened steel with a clean, welded finish and a dull zinc coating for weather protection. There’s no rattle or play—just a solid, compact mass of metal. It’s immediately clear that this chain was not built for convenience; it was built for one purpose: to be an absolute nightmare for thieves. The first thing we did was test it with several high-quality padlocks from our collection, confirming that the end links are accommodating enough for most standard and high-security shackle sizes. You can see its full specifications and compatibility details to ensure it fits your chosen lock.

Performance Deep Dive: Putting the Yarlung Chain to the Test
A security chain’s worth is measured not by its looks, but by its ability to withstand punishment. We spent considerable time evaluating the yarlung 2 Feet Security Chain Heavy Duty based on its core attributes: its raw material strength, its protective features, and its real-world usability. Our findings reveal a product that excels in its primary mission of security but demands careful consideration from the buyer regarding its application.
Unpacking the Brute Force Resistance: Hardened Square-Link Steel
The star of the show is undeniably the chain itself. Composed of 3/8-inch (approximately 9.5mm, though Yarlung markets it as 10KS) hardened alloy steel, this chain falls squarely into the heavy-duty category. In our experience testing security devices, this thickness is the critical threshold where common hand tools like bolt cutters begin to fail spectacularly. The true genius of the design, however, lies in the square-shaped links. Unlike round links that provide a perfect concave surface for cutter jaws to bite into, square links present flat edges. When a cutter applies pressure, the force is distributed awkwardly, often causing the jaws to slip or be unable to gain the leverage needed to make a cut. This is a design feature that really sets it apart from lower-end chains, and you can explore this superior square-link design further online.
During our hands-on evaluation, the sheer heft and rigidity of the links were palpable. Each link is cleanly welded, leaving no obvious weak points for prying or twisting attacks. We subjected it to simulated abuse with pry bars and hammers, and it showed no signs of deformation. While we don’t perform destructive cutting tests with angle grinders (as no consumer-grade chain can withstand a sustained attack from one), its performance against manual tools is what matters for opportunistic theft. The hardened steel is designed to resist hacksaws, and in our tests, a standard blade barely scratched the surface, producing more noise than progress. This is the kind of robust construction that provides genuine peace of mind, knowing that a casual thief with a pair of cutters in their backpack will be completely and utterly defeated.
The Unsung Hero: Protective Sleeve and All-Weather Durability
While the steel provides the muscle, the external features ensure the chain lasts and doesn’t damage what it’s protecting. The black nylon sleeve is more than just a cosmetic touch. It’s a thick, rugged material that immediately reminded us of the sheathing on high-stress towing or winch equipment. Its primary job is to prevent the heavy, angular steel links from chipping the paint on your bike frame, motorcycle swingarm, or powder-coated gate. We aggressively rubbed the sleeved chain against a painted metal surface, and it left no marks, proving its effectiveness. This is a crucial feature for anyone looking to protect a valuable asset with a pristine finish.
This protective sleeve also contributes to the chain’s discreet appearance. As one user noted, they purchased it for a community stormwater pond gate, and the black sleeve blended in perfectly, avoiding an overtly industrial or unsightly look. Underneath this sleeve lies the second layer of defense against the elements: a zinc coating on the steel itself. This galvanization process is vital for preventing rust and corrosion. We left the chain outdoors through several rainy days and nights, and it showed no signs of oxidation. This combination of a physical fabric barrier and a chemical anti-corrosion coating means the yarlung 2 Feet Security Chain Heavy Duty is exceptionally well-suited for permanent outdoor installations, like securing a trailer in your driveway or a gate on your property. This level of durability is a key selling point, and you can check the latest price and availability for this all-weather security solution.
The Double-Edged Sword: The 2-Foot Length and Its Practical Implications
This is the single most important factor to consider before purchasing this chain, and it’s where our expert opinion aligns perfectly with user feedback. The 2-foot (24-inch) length is both the chain’s greatest strength and its most significant limitation. From a pure security standpoint, a shorter chain is superior. It forces you to lock your bike or equipment tightly against an anchor point, leaving no room for a thief to insert a car jack for a leverage attack or to get enough slack to reposition their bolt cutters for a better angle. It creates a compact, tight, and frustrating puzzle for any would-be thief.
However, this same feature makes it highly specialized. As one user wisely cautioned, you must “KNOW FOR CERTAIN you’ll only need 2 feet and no more.” We found this to be absolutely true in our testing. The yarlung 2 Feet Security Chain Heavy Duty is perfect for specific scenarios: locking a single bike frame and rear wheel to a standard U-shaped bike rack, securing a spare tire to a vehicle’s frame, or chaining a generator to the leg of a heavy workbench. It excels in these close-quarters applications. But if you hope to lock your bike to a thick lamppost, a tree, or even some wider, decorative street poles, you will find yourself frustratingly short. We attempted to lock a mountain bike to several common urban objects and were successful only about half the time. This limitation is not a flaw in the product but rather a defining characteristic. It’s a specialist tool, not a one-size-fits-all solution. If your daily locking needs are predictable and compact, this chain offers a level of focused security that longer chains can’t match.
What Other Users Are Saying
Scouring feedback from other buyers, a clear and consistent picture emerges that mirrors our own findings. The positive sentiment overwhelmingly centers on the product’s incredible build quality. Users frequently use words like “heavy,” “dense,” and “very heavy duty” to describe their initial impressions. One customer who purchased it to secure a gate at a community pond praised not only its strength but also the discreet black sleeve that “blends in with the gate,” highlighting its suitability for permanent outdoor fixtures where aesthetics matter.
On the other side of the coin, the most common piece of critical feedback—or rather, strong advice—revolves around the length. A particularly insightful user review stated, “I’d recommend buying 3 feet instead. Unless you KNOW FOR CERTAIN you’ll only need 2 feet and no more.” They went on to explain that they were “unable to use it for most things because of the length.” This isn’t a complaint about quality but an essential piece of practical advice for potential buyers. It confirms our assessment that this is a purpose-built chain for specific, compact locking scenarios, not a versatile, all-purpose security device.
How Does the yarlung 2 Feet Security Chain Heavy Duty Compare to Alternatives?
The yarlung 2 Feet Security Chain Heavy Duty occupies a specific niche focused on maximum material strength in a minimal length. To understand its value, it’s crucial to see how it stacks up against other popular security options that prioritize different features like integrated locks, longer reach, or unique form factors.

The Honszex lock is a completely different approach to security. Instead of a traditional chain-and-padlock system, it uses a unique handcuff design. This makes it incredibly fast and convenient for securing e-scooters or bikes to smaller poles and racks. Its main advantage is speed and ease of use. However, the chain links are significantly thinner and it lacks the raw, intimidating presence of the Yarlung. A user might prefer the Honszex for its portability, included waterproof bag, and all-in-one design, especially for quick stops where convenience is more important than fortress-like security. The Yarlung is for the user who is willing to sacrifice that convenience for superior brute force resistance.

The Mezelon is a more direct competitor, offering a traditional chain lock design with an integrated key lock. At 8mm, its chain links are a step down in thickness from the Yarlung’s robust 3/8″ (9.5mm) links. This makes the Mezelon lighter and potentially more manageable, but it also places it in a lower security tier. It’s better suited for medium-risk environments. A buyer would choose the Mezelon if they want the simplicity of an integrated lock system and are looking for a good balance of security and affordability, without needing the extreme cutting resistance offered by the thicker Yarlung chain. The Yarlung is the choice for those who want to bring their own high-security padlock to the party and demand the thickest possible steel.
3. Kryptonite Keeper 790 Combo Bike Chain Lock 3 Feet
- End link locking point for extensive holding power
- 4-sided 3t manganese steel chain links
- 4-digit resettable combination over 10, 000 codes
Kryptonite is a titan in the bike security industry, and the Keeper 790 represents a focus on user-friendly features. Its two biggest advantages over the Yarlung are its longer 3-foot length, which offers far more locking versatility, and its integrated 4-digit combination lock, eliminating the need to carry keys or buy a separate padlock. However, the chain links on the Keeper series are typically thinner (7mm) than the Yarlung’s. A cyclist would choose the Kryptonite for its trusted brand name, longer reach, and the convenience of a combination lock. It’s an excellent all-around choice for daily commuting. The Yarlung, by contrast, is for the security purist who sees an integrated lock as a potential weak point and prioritizes the sheer strength of the chain above all else.
Our Final Verdict: Is the yarlung 2 Feet Security Chain Heavy Duty Right for You?
After extensive hands-on testing and analysis, our verdict on the yarlung 2 Feet Security Chain Heavy Duty is clear: this is a superb, specialized security tool for those who understand its limitations. It is not an all-purpose bike lock. It is a compact, unyielding length of hardened steel designed for maximum security in tight spaces. Its brute-force resistance, thanks to the 3/8″ thick, square-link hardened steel, is exceptional for its price point and will deter all but the most determined, tool-equipped thieves. The durable nylon sleeve and weatherproof zinc coating make it a reliable choice for long-term outdoor use.
We recommend this chain wholeheartedly to users with a specific, predictable locking need: securing a bike to a dedicated rack, locking down a generator or trailer, or adding a layer of high-density security to a gate. However, if you need the flexibility to lock your bike to a wide variety of urban objects of differing sizes, its 2-foot length will be a constant source of frustration. For the right user, this chain is an unbeatable value. If you have measured your needs and this compact powerhouse fits them, you will be investing in a truly formidable piece of security.
