Our custom-made SecurityForBikes RL21 RoundLock super-compact padlock has been designed to fit our Protector chains. It also doubles as a motorcycle disc-lock.
Independently tested to Sold Secure Motorcycle Gold and Pedal Cycle Diamond standard. It's small but mighty!
The RoundLock has been designed to be difficult to tamper with and gives thieves very little to target. Its beefy 21mm pin is encased in a compact body that spins, making it very hard to defeat. It features a disc detainer anti-pick cylinder with 9 discs, protected by a rotating anti-drill hardened alloy steel plate.
It offers almost impenetrable resistance against common attack methods, including angle grinders, hammering, freezing, and drilling.
We think this lock offers unbeatable bang for your buck!
Key Options
We offer two different key options: Keyed Different and Keyed Alike. If you want multiple locks on the same key, please order Keyed Alike. If you only need one lock, please order Keyed Different.
Please note: we cannot currently match your existing lock key number.
RL21A Chamfered Socket
We also produce a socket with a chamfered edge, this is called the RL21A. While the standard Roundlock works well with all of our chains, the RL21A makes it slightly easier to use the Roundlock with our 19mm chains and chains from other manufacturers which have slightly different link dimensions. When selecting this option, we will send you an RL21A socket instead of a standard socket.

Chain options
We recommend this padlock with the Protector 13mm and 16mm chains. It will fit the Protector 19mm chain, however, we also sell a RoundLock Adapter called the RL21A. This adapter has a chamfered edge and can be used instead of the standard-issue socket, giving you slightly more clearance and making it easier to fit the lock to the 19mm chain in a wider variety of applications.

Great products
Thanks for some great products. Your kit protected my bikes perfectly during a burglary a few years ago and it’s still going (extremely) strong.

Still going strong
I bought from you once and only needed to buy once in 2016, but suffice to say that the 19mm bespoke length chain, and ground anchor installed according to Pragmasis instructions are still going strong, keeping my bike safe just off the street in Brixton, London.
Mr B
Wholly impressed
I would like to say I am wholly impressed with the ground anchors, chains and padlocks that I have purchased over the past few years and will always recommend you when the opportunity arises.

Excellent quality piece of kit. Our second anchor to date. Exceptional service. Nice to see a British company up there supplying quality goods and customer service

Top class service
This is a serious chain! I certainly feel more comfortable that my bikes are well secured. Very pleased with the service too. I phoned then placed an online order and my chain arrived the next day. Excellent product and 1st class service. Thank you!
