D83 - Narrow stile mortise lock with hook bolt with 3 locking points

D83 narrow stile mortise locks have a cylinder locking mechanism (compatible with Euro-profile or cross key cylinders) with 3 locking points (center, bottom and top) connected by a single front. They are designed for mortise installation on aluminium doors.

They have a swinging or hook bolt and a reversible design for use on right and left-handed doors. They are available in 25 to 35 mm backset sizes. The supplied face plate can be flat or U-shaped.

They are available in 2 different versions to suit different locking requirements:

• with latch and bolt;
• with hook bolt only

In the latch and bolt version, the latch can be replaced with a roller (the two accessories are interchangeable) or the latch can be removed and the model converted to a standard deadbolt-only version by occluding the hole with the cap provided. The depth of the latch and roller are adjustable.

The D83 lock's latch has a Comfort system that not only reduces the noise of the door closing, but also limits wear on the striking plate and minimises friction.

Finish: Galvanised steel (lock) - Stainless steel (face plate cover)
