Security Chain

A security chain is only as good as the links it’s made from. This one uses hardened steel anti-crop square links, which resist the leveraged cutting action that standard round-link chains struggle against. The outer nylon sleeve keeps the chain from scratching paintwork, powder coatings or any surface it’s resting against — useful when you’re chaining a bike to a rail or a machine to a post and you’d rather not explain the marks afterwards.

Available in 1m, 1.5m and 2m lengths in 8mm diameter, so you can pick the right reach for the job rather than coiling up unnecessary slack. All three sizes share the same link construction and sleeve quality. The difference is purely practical: 1m works for compact situations, 1.5m gives you a bit more flexibility, and 2m is the one to reach for when you’re threading through awkward frames or looping round multiple items at once.

Where This Security Chain Gets Used

On site, this type of chain is a daily-use item. It goes through ladder rungs, around scaffold poles, through generator frames and over motorbike wheels. It’s the kind of thing that lives in the back of the van and earns its keep every time someone tries a door they shouldn’t. The nylon sleeve is a practical addition rather than a cosmetic one — it stops the chain from rattling against metal surfaces and keeps it from marking anything valuable it’s in contact with.

Pair this security chain with a solid closed-shackle padlock rated to the same security level and you’ve got a combination that’s genuinely difficult to defeat quickly. A chain is a deterrent as much as a barrier — the harder it looks, the less likely anything is to happen in the first place.
