Heavy Duty Magnetic Morticed Deadlock - Single Action
Purpose
To provide secure deadlocking of sliding doors or gates where an enhanced level of security
is necessary. This lock is specifically designed for very high use applications; typically securing internal doors and main access routes.
Overview
The 3M56 Mark 3 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 deadlocking operated by a unique key profile. 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:
Pass Key. Locking is achieved by inserting the pass key into the dished keyhole and rotating fully in a clockwise direction, this action
will extend the anchor bolt to expand the reinforced hooks to their fully thrown position.
Unlocking is achieved by inserting the pass key into the dished keyhole and rotating fully in an anti-clockwise direction, this action
will withdraw the anchor bolt and retract the reinforced hooks to their rest position.
