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.

Accreditations:

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).

Using the Roundlock as a Disc Lock:

The RL21 RoundLock doubles as a very compact and convenient disc lock, and as it weighs just 0.55kg it`s easy and practical to carry. 

The RoundLock is acknowledged by Bennetts as pretty much indestructable and a great value disk lock, however, if ordering it to use it as a disc lock, please ensure that there is a large enough aperture through the disc brake to accommodate the 21mm Pin element of the lock body and that the 15mm Vertical Shackle Clearance is OK for your applicaton.

It is suitable for use as a motorcycle disc lock for most motorbikes, but may not suit some motor scooters which have smaller apertures to fit through.

Using the RoundLock with a Security Chain:

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). Keyed Alike RoundLocks are a great option for those using a RoundLock with their security chain, and another unit as a motorbike disc lock. 

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.

Keyed Alike Option: We are able to offer the Roundlocks in a Keyed Alike option to save having multiple keys, however this option is only available when purchasing together and cannot be retrospectivly matched to key patterns from previous orders.
