Union 2077 5" Horizontal Mortice Sashlock, The Lock features the usual deadbolt which is operated by the keys. The latch is set to the far side of the lock which enables the knob or handles to be further away from the edge of door, especially useful when you have a deep slamming strip/rebate on your door such as a 1 Hr. Fire door which makes it easier to operate the handles without bumping or trapping your hand/fingers These locks are new old stock, a little dusty but in good condition - being old they feature much better components inside than later versions where they have cheapened them up!!! These have mostly heavier all brass parts. Boxed in 5's and individually wrapped in paper so don't expect them in fancy wrapping/packs.
