Premium Quality: Our security chains are made of hardened steel with a special anti-corrosion coating which makes them ideal for outdoor use. Each link has a thickness of 5/16", inside height of 1 3/8" and inside width of 1/2".This chain requires 6 tons of cutting force to break through the hardened steel.

Theft Deterrence: Our chain cannot be compromised by typical aggressive burglary attacks. Each individual link is unique in that the shape is squared rather than round. The squared link construction makes it almost impossible for theft tools to get a secure grip on the chain to cut. The thick hardened steel is extra resistant to sawing and the welded finish makes prying insurmountable.

Secure Anything: ABUS square link security chains are utilized by both industrial and consumer users. Our customers trust this chain to secure their commercial/residential properties, containers, bikes, gates, fences, trailers, ATV’s, motorcycles and much more.
