BRITON 5730 DIN Standard Fire Rated Bathroom Lock Case 60mm Backset

The Briton 5730 DIN Standard Bathroom Lock Case is an essential choice for ensuring privacy in bathroom doors and similar applications. This lock case is engineered for reliability and ease of use, featuring a latchbolt that can be operated by lever handles from both sides. A simple turn of the thumbturn activates the 20mm deadbolt, while an outside emergency release provides peace of mind for quick access in urgent situations.

Designed with a 60mm backset and 78mm centres, the Briton 5730 is ideal for both commercial and architectural door applications. Its quick reversible profiled latch allows for flexible installation, and the bolt-through fixing holes comply with DIN 18251 standards. The lockcase is constructed from galvanised steel with a satin nickel plating, ensuring durability and corrosion resistance.

This lock is also compatible with FD30 and FD60 fire doors, having been fire tested to EN 1634-1. To maintain the fire rating, it is crucial to fit the lock with the appropriate intumescent pack, and a suitable door closer must be installed if used on a fire door.
