The Alpro Europrofile Hook Bolt Deadlock 52220XX is a narrow style design. It is used primarily within the commercial aluminium door sector and the design of the lock allows a bolt to be thrown into a lock keep. The bolt cannot then be operated without the use of the authorised key.
Europrofile cylinder deadlocks provide security deadlocking for a variety of aluminium doors including swinging and sliding applications.
The Alpro 52220 hook bolt is constructed from stainless steel and is a 5 ply laminated construction, with the centre core case hardened, complete with hardened roll pin to resist hacksaw attack. All locks are designed to accept standard profile cylinders or thumbturns.
