*New* Protector 25mm Titan Long-Link absolutely huge uncroppable hardened steel security chain (select length below), plus Squire Stronghold SS80CS-XLN ultra heavy duty padlock. The biggest and beefiest production security chain in the world, as far as we know, plus an incredibly strong padlock. This pairing has a superbly close fit between the lock and the chain - Minimum clearance for any type of attack, even including angle grinders!

European Boron steel.

Please beware that this is an extremely heavy duty chain and it is suitable for only the most severe security applications. It is almost twice the weight of our 19mm chain, and that is already heavy duty! Please do not order this unless you are confident that you really need such an extreme chain, and that you are going to be able to handle it and fit it through whatever item(s) you need to secure. It is a beast! We reserve the right to make a restocking charge if you order it and then need to return it.

Note that this is a long-link chain so the end links should be interlocked in order to fit the lock, as for most of our Protector range of chains.

Sold Secure Motorcycle ("Powered Cycle") Diamond for the chain, and Motorcycle Gold for the lock.

Please Note: This is a specialist item and stock may be limited in some lengths, and other lengths may be available at times.

The lock is usually supplied with the R1 restricted key profile (except when matching a previously-supplied alternative profile lock via the Keyed-Alike option).

The chain is 11kg/metre.

Please note: The SS80CS-XLN is an ultra heavy duty lock that weighs 2.2kg for the lock on its own! Neither the lock, nor the 25mm Titan chain, are recommended except for extreme situations where the absolute ultimate deterrent is required.

Please note the lock deliberately only fits a single link of the chain. We have a video showing how to interlock the end links of the chain in order to fit the lock.

Price given will adjust as you select alternative lengths below.
