Description: HORIZONTAL 2-BOLT MORTICE LOCK
To provide secure locking, (with latching facility) of hinged wooden doors in shops, offices, institutions etc., where master-keying and/or, suiting with other Chubb 'Castle' range locks is a requirement, or where a knob action with ample space (to clear rebated frame for example) is preferred.
Mortice lock with formed-up case and welded Forend. Flat cap screwed to pillars in case. Horizontal construction with follower for handle at same level as keyhole.
Deadbolt operable by key only from either side (full turn to lock or unlock). Latch released by knob/handle only from either side, but will re-engage without the use of the knob/handle, under light door closing force.
Although the lock does not carry the BS3621 Kitemark, it is, nevertheless, designed and manufactured to a similar, and in some ways higher, standard viz:- (BS3621 requirements denoted by *).
After undergoing wear test lock will not (unless deliberately suited to do so) pass a key differing by one step up or down in any lever position*.
The bolt will resist a hacksaw attack of at least 5 minutes (actual sawing time), during which 2 new 300mm hacksaw blades may be used*.
After undergoing hacksaw test the lock, mounted in a hardwood block as described in BS3621, will resist a side load of 13,500N applied 3mm away from the forend. (Load applied from either side)*.
Locking plate will similarly resist a side load of 13,500N*, and locking box (protecting the end of the bolt) will resist an end load of 9,000N*.
Bolt will deadlock against an end pressure of 15N*. and ensure a projection of at least 14mm* when thrown.
Deadlocking mechanism strong enough to resist an end load, on the bolt, of 1,200N*.
5-lever (all differing) locking mechanism, with 9 lifts/lever affording at least 25,000 usable differs (before suiting) without using weak upstanding steps or resorting to warding.
False notching and common belly form on all levers to deter reading and manipulation attacks.
Key thrower with curtain, and special shield, to greatly restrict access to any part of the locking mechanism and further frustrate attempts to read or manipulate the lock.
Internal components designed to distort or collapse under strong key attack, but in such a way as to leave the lock secure.
Lock capable of performing the following operations without loss of function and without incurring undue wear in any part:
60,000 bolt withdrawals using key*
300,000 latch withdrawals via the follower**
** = BS5872 (Cat A) requirement
Integral brass keys (on standard locks) with no weak upstands
2-way action follower for use with knob furniture as well as handles.
