What is a Heavy Duty Tubular Deadbolt?
Dead bolts are a type of lock that is operated solely by a key. While these products don't include a latch, they can be used in conjunction with a separate tubular latch, or as a standalone item.
Most often, a deadbolt is used alongside a rim lock and door knob set on external doors.
All our dead locks are British Standard, meaning they're rated highly enough to be recognised as adequate protection by insurance policies.
