Lockwood Matt Black Symmetry Double Cylinder Deadbolt

The Lockwood Symmetry Double Cylinder Deadbolt is operated by key from both inside and outside. The 60-70mm adjustable backset and 54mm hole size make it a straightforward retrofit for most existing deadbolt holes, and it suits doors 31-45mm thick, with a spacer ring included for doors 31-41mm. Designed to complement the Lockwood Symmetry knob and lever lockset range, it can be keyed alike with them for a single-key household. Backed by Lockwood, an Australian brand with over 90 years of locksmithing experience.
