LOB TZ51 Surface-Mounted Latch Lock Graphite for Doors 32-64mm Self-Locking

Product Overview

The LOB TZ51 surface-mounted latch lock is designed for securing doors in residential and light commercial environments. It features a single-cylinder mechanism and a self-latching function, automatically locking the door upon closure, making it suitable for spaces where regular access control is required. The lock body and strike plate are made from stamped steel with a powder-coated graphite finish for corrosion resistance.

Unlike generic latch locks, the TZ51 offers compatibility with door thicknesses ranging from 32 mm to 64 mm, accommodating a wider variety of entry doors without need for spacer kits or custom modifications.
