What We Do
Most Break-Ins Beat the Door, Not the Lock
A fancy cylinder means little if the frame splits with one kick. We harden the whole assembly: Grade-1 deadbolt, 3-inch screws biting deep into the stud, a reinforced strike box, and optional hinge and jamb armour — fitted flush so it still looks like a normal, handsome door.
Ideal after a break-in nearby, for ground-floor flats, rentals between tenants, or anyone who just wants to sleep sounder.
