NEW: Protector 19mm ultimate uncroppable hardened boron steel chain (select length below), plus the super-compact RoundLock with both RL21 and RL21A sockets (compatible with 16mm and 19mm chains, respectively). 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 6.3kg/metre; the RoundLock combo is another 0.8kg. 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).

This package includes the standard RoundLock RL21 socket and also the RL21A socket, allowing a beautifully close fit with 16mm and 19mm chains, respectively. The RL21A socket is custom-made to suit the Protector 19mm chain.

The RoundLock can also 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.

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Please note that the Protector 22mm Titan chain shown in the above video has been superseded with a new, even tougher, version.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.

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:

The first thing you notice is what a beast the 19mm Pragmasis chain is. Heavy, solid and rugged. It fills you with confidence. This is only for home or office use. Then the design and quality of the RL21A lock is exactly how its been described by online r...

Very solid chain and lock

Read about this in Bennetts motorcycle lock tests where it was very highly ranked. Initially ordered a 1.5m chain but I managed to slightly mis-measure the distance between the lamppost and the curb so had to go for a 2m. In any case, the customer support...

This chain and lock is way better than I was expecting, so pleased I chose this brand.
Big beefy and definitely doing the job it’s designed for, million times better than I’ve seen else where. A must have item for sure.
