ABUS 3/8" Thick Square-Link Security Chain, 2' Hardened Steel with Nylon Sleeve and Anti-Corrosion Finish

The ABUS 10KS 3/8" thick square-link security chain is a heavy-duty, 2-foot hardened steel chain with a nylon sleeve and anti-corrosion finish designed to resist tool attacks and protect finishes.

Built for demanding outdoor environments, this ABUS chain combines a hardened steel core, square-shaped links, and a protective sleeve to deliver physical resistance and finish protection. Its design focuses on slowing or deterring common aggressive attacks while minimizing surface damage to whatever you lock — from motorcycles to gates and storage units. The chain balances robust construction with weather-resistant coatings so it stays usable and visible in wet or salty conditions.

How does the square link shape improve security?

Square links change how cutting and leverage tools engage the chain compared with round links. Flat surfaces reduce the bite and purchase points for bolt cutters and saws, increasing the difficulty and time required for forced entry attempts.

• Square cross-section links reduce tool grip and shear action.
• Hardened steel construction resists cutting and deformation.
• Thicker 3/8" link material adds mass and cutting resistance.

Will this chain stand up to outdoor exposure and corrosion?

The 10KS chain is treated with an anti-corrosion coating and fitted with a nylon sleeve to protect both the metal and the object it secures. Those features help prevent rust, reduce wear from weather, and keep the chain looking intact for longer when used outdoors.

• Anti-corrosion coating resists moisture and surface oxidation.
• Nylon sleeve shields paint and chrome from scratches and scuffs.
• Suitable for exposed locations such as yards, driveways, and racks.

What size, weight, and compatibility should I expect?

This model ships as a 2-foot length of 3/8" thick square link chain, roughly weighing 14 pounds, intended for pairing with robust padlocks. Its dimensions and mass make it suitable for high-value items where a heavy chain is warranted.

• Length: 2 feet (0.61 m) standard for compact, high-security applications.
• Thickness: 3/8" square links for enhanced cut resistance.
• Weight: approximately 14 lb — pairs best with heavy-duty padlocks.

How do I use this chain effectively without damaging my property?

The nylon sleeve limits metal-on-metal contact, so wrap the chain around the object and anchor point so the sleeve covers high-contact areas. Choose an appropriately rated padlock and avoid sharp bends that expose bare steel.

• Keep the sleeve between chain and painted surfaces to prevent scratches.
• Use a high-security ABUS padlock or Granit series lock for best pairing.
• Avoid knotted or overly twisted placement that exposes link edges.

Who is this for: The ABUS 10KS 3/8" square security chain is aimed at owners of motorcycles, bicycles, gates, trailers, and outdoor equipment who want a compact but heavy chain that resists common attack tools and protects finishes. It fits users who prefer a short, high-mass solution to secure items in exposed or high-risk settings and who will pair it with an equally rugged padlock for best results.
