## Description

Upgrade bathroom privacy in minutes with our 3-inch (76 mm) Mortice Tubular Deadbolt—purpose-built for toilet, en-suite and cloakroom doors. The solid steel bolt delivers a secure, wobble-free close, while its precision-ground mechanism keeps every turn whisper-quiet, eliminating clangs that disturb the household. Designed for UK interior doors, the latch body drops straight into the existing 54 mm or 25 mm bore; a reversible latch tongue means it fits left- and right-hand setups without extra parts. We machine the faceplate and strike from 304 stainless steel, then seal them in a satin finish that shrugs off steam, cleaning products and everyday fingerprints. No peeling, pitting or rust—just long-lasting good looks. Everything you need ships in the box: adjustable faceplates (60 mm & 70 mm), strike plate, dust box and colour-matched screws. Follow the illustrated guide and you’ll have dependable bathroom privacy in less than a coffee break—no chisel, no carpenter, no stress.
