NEW: Our custom-made SecurityForBikes DIB-Series compact D-Locks.

This is a genuine motorcycle-grade D-Lock, with true 16mm thick steel shackle. Double-locking and guaranteed impossible to bolt-crop by hand.

Available in two compact sizes:
130mm x 87mm internal clearance; and 190mm x 87mm internal clearance,
plus a conventional size:
260mm x 87mm internal clearance.
It is usually a good idea to use the smallest size that will do the job.

Sold Secure Motorcycle Gold/Quad & ATV Gold/Bicycle Gold/Motor Scooter Gold approved with any appropriately-approved chain and also on its own. Also Police Preferred Specification.

16mm diameter hardened steel shackle plus rubber covering (18.2mm diameter overall, including the rubber sheath). Heavy duty hardened steel lock tube with improved design alloy insert (not plastic, like some competing products!!!).

Disc detainer anti-pick cylinder with 9 discs, protected by rotating anti-drill hardened alloy steel plate.

3 keys supplied.

Keyed-alike available at initial order only (not available retrospectively) when ordering more than one lock together, and only amongst other RL21(A) locks and/or DIB-Series D-Locks. These locks can't be keyed-alike with any of the Squire locks.

Weight: 1.5kg (for the 130mm version; 1.7kg for the 190mm version and 1.92kg for the 260mm version).

Sliding keyway cover to keep dirt out of the cylinder.

Very versatile and a perfect partner for Protector 16mm/13mm/11mm chains at a great price! Particularly suitable as a portable security option for motorbikes and high-value bicycles, either when locking the bike frame directly to something solid in the scenery, or when partnered with a suitable chain (and even a noose chain).
