Heavy Duty Morticed Hookbolt Lock - Single Action
To provide secure deadlocking of sliding doors or gates where a superior level of security
is necessary. This lock is specifically designed for very high use applications; typically
securing perimeter, internal doors and main access routes.
The 3M222 magnetic lock affords a higher level of security due to the inability to sight
read keys. The magnetic key code is impossible to read or duplicate using normal human
senses alone or duplicate with standard workshop equipment.
The 3M222 is a mortice hookbolt of robust construction. Twin locking laminated and hardened hooks are used to provide positive engagement in the frame with maximum strength.
The lock provides a single throw only, however, the lock can be configured to work from the following key types: master key only, servant key only or pass key only.
The lock is operable from both sides and the escutcheon is designed to allow only the correct key profile being inserted into the lock.
Secure locking is achieved as follows:
Locking is achieved by inserting the designated key into the keyhole and turning the key through 90o in an anti-clockwise direction.
The anchor bolt is then extended by turning the handle which will expand the reinforced hooks to their fully thrown position. Unlocking is achieved by inserting the designated key into the keyhole and turning the key through 90o in an anti-clockwise direction. The
anchor bolt is then withdrawn by turning the handle which will retract the reinforced hooks to their rest position
