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Please note that the Protector 22mm Titan chain shown in the above video has been superseded with a new, even tougher, version.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

19mm chain and round lock

- 19/11/2021

Top quality chain an absolute beast wrapped in a good quality sleeve with a round lock and a torc ground anchor brilliant communication with the staff came well packaged tracked with parcel force and a day earlier thank you very much.

Really big chain.

- 28/10/2021

Forget your chains you can pick in up in certain retail stores. This is a really big and heavy chain and having researched through online videos, both this and the Roundlock are a perfect deterrent for locking your bike at home.

Fantastic quality package

- 18/10/2021

Obviously it goes without saying, but this is a heavy duty chain, with emphasis on the heavy, so not one to be taking out on the bike. In situ in the garage it's an excellent deterrent, but one that'll likely only fit through your wheel and not the swing-...

Pragmasis Takes Security Serious

After researching options offered on the web to secure my motorcycle in the garage, bought a 19mm chain, 2 roundlocks and a Double Doofer ground anchor . All were dispatched immediately. Service second to none as is quality of the products. The roundlock...
