RoundLock Sold Secure Motorcycle Gold Dumbbell Type Lock

We have long been fans of the Dumbbell style of padlock, which when used appropriately with a security chain, prove highly effective and very difficult to attack.

We are therefore delighted to add the High Security RL21 RoundLock to our range, which has achieved "SOLD SECURE MOTORCYCLE GOLD" accreditation and is ideally suited to use with our serious security Protector Chains (13mm, 16mm or 19mm chains).

The RL21 RoundLock Pin Element of the lock body is 21mm in diameter, which means that the lock even doubles as a very compact and convenient disc lock, and as it weighs just 0.53kg it`s easy and practical to carry.

The RL21 is designed for use with Protector Chains up to 19mm, although the standard lock can only be used with chains up to 16mm and you will need the additional special RL21A socket if you want to use the lock with the 19mm chain. The RL21A socket is available to buy as a separate item, or there is a special bundled pack which includes the standard RoundLock plus the RL21A socket.

The lock comes with three keys as standard, and locks can be keyed alike to other RoundLocks for a small extra charge (please call us; 01273 475500 to discuss your needs).


Resistance to attack

When tested in use with a 19mm Protector Security Chain by Bennetts - the Bike Insurance Specialists in Oct 2017, this was the result;

...the RoundLock is an excellent piece of kit, fitting snugly against the edges of the chain`s links, making it very difficult to attack.

When attacked with a sledgehammer, the lock merely deformed (the shape of the lock itself makes it very difficult to hit squarely).

It`s inaccessible with bolt croppers, and is so thick that an angle grinder attack causes little damage – in fact the chain is the easier option for a crook to attack ...and that is also a very tough cookie to crack!


Please Note: PD RL21 & 21A Roundlocks are not suitable for use with our 14mm Quadlink Chain as the shackle is too large to fit through the chain links.
