Mason, the world's lightest Sold Secure Diamond rated bike lock, now available in compact 140mm or 180mm triangulated shackle lengths, and long 220mm or 300mm pentagonal shackle lengths.


The compact 'mini-D' configuration is ideal for securing a single bike in theft prone areas. The high level of security is achieved by use of a unique triangulated 17mm thick shackle for the best strength to weight ratio. The Longer Mason locks adopt a complex 15.3mm thick patented pentagonal hardened steel shackle which is also the widest of its kind, ideal for securing multiple bikes.

Every Mason lock features a double deadbolt crossbar locking mechanism for protection against twist attacks and an anti-drilling key cylinder. Seatylock have ensured lasting durability by using rust free hardened steel and a rattle free dampened design.

Mason is ideal as a theft deterrent for longer duration security in city centres and other locations where stealing a bike may go completely unnoticed. Other suitable applications include additional home security used in conjunction with a ground anchor in the event of a garage break in, and higher value protection for e-bikes or motorbikes.

Don't be an easy target. Seatylock, for the bike you love!
