Overview

The 3F56 is a mortice lock of robust construction based on the Chubb Locks Custodial Services large mortice footprint. The main bolt is automatically extended providing a 32mm throw and deadlocked on closure of the door (4.8mm gap maximum - forend to mating surface).

Secure unlocking / locking is achieved as follows:

Unlocking is achieved by a partial turn of the servant key which lifts the internal blocking mechanism enabling the withdrawal of the main bolt by the handle. The bolt is then retained automatically when fully retracted and the door is out of frame.

Locking is achieved automatically; on closure of the door the brass snib bolt is depressed on contact with the strike plate mounted to the frame, this then releases the main bolt. Deadlocking occurs when the main bolt is fully extended allowing the internal blocking mechanism to engage.

Use of the master key (by rotating the top of the key towards the front of the lockcase when the ILU bolt is in the locked position) will further extend the ILU bolt which disables use of the servant key. The servant key can be re enabled by rotating the top of the master key towards the rear of the lockcase.
