NEW: Protector 16mm uncroppable hardened boron steel chain (select length below), plus the super-compact RL21 RoundLock.

The chain is Sold Secure Motorcycle Gold (in fact, it is Sold Secure Gold in every category) and the RoundLock is Sold Secure Motorcycle Gold/Quad & ATV Gold/Bicycle Gold/Motor Scooter Gold approved. The chain is 4.5kg/metre; the RoundLock padlock is another 0.6kg. The chain is supplied with usually bronze colour sleeving, and the chain itself is finished with either zinc plating or a black finish.

3 keys supplied.

Keyed-alike available at initial order only (not available retrospectively) when ordering more than one lock together, and only amongst other RL21(A) locks and/or DIB-Series D-Locks. These locks can't be keyed-alike with any of the Squire locks.

The RoundLock is not suitable for our 19mm chain unless the optional extra RL21A socket is also purchased and that is used in place of the standard RL21 socket. The RL21A socket is available separately - Please Click for the RL21A Socket product listing.

The RoundLock can also sometimes be used as a motorcycle disc lock - Check that you have a suitable opening that will take the 21mm diameter shackle in your brake disc or disc carrier. You can then use this with a chain when at home and as a disc lock when out and about. Note that disc locks do not prevent a bike from being lifted into the back of a van, which is a common technique employed by thieves.

Noose chain option has a special oversize ring at one end of the chain (only), allowing a noose to be formed by looping the chain through that ring. This is helpful with longer lengths of chain, avoiding the normal need to make a big loop around all items - A noose can be formed at the ground anchor and a second loop formed with the lock at the other end of the chain.

Price and weight shown are for the package including a 2.0m long chain - Please select alternative lengths below and the price displayed will be adjusted automatically.

The following video gives a quick visual overview of the whole Protector range of chains, from the ultimate Protector 22mm Titan chain, through to the Protector 11mm:

Please note that the Protector 22mm Titan chain shown in the above video has been superseded with a new, even tougher, version. The video will be updated as soon as possible. We apologise for any confusion in the meantime.

This video describes the Noose chains option:

Below is a short video overview of the SFB RoundLock, showing how it can be used with our Protector 16mm and 13mm chains and, with the optional RL21A socket, with the 19mm chains:
