BRITON 5750 DIN Standard Fire Rated Euro Nightlatch Case 60mm Backset

The Briton 5750 DIN Standard Euro Nightlatch Case is an exceptional choice for front entrance doors requiring key operation from the outside. This lock combines functionality and security, making it ideal for both commercial and architectural applications.

With its single euro cylinder, the latchbolt is easily operated with just one turn of the key. The design omits a holdback function, ensuring secure nightlatch operation.

Key specifications include a 60mm backset and 72mm centres, along with a quick reversible profiled latch for added convenience. The robust construction features bolt-through fixing holes compliant with DIN 18251, a galvanised steel case with satin nickel plating for enhanced corrosion resistance, and a grade 316 stainless steel forend available in both round and square options.

This lock is not only practical but also fire-tested to EN 1634-1 standards and Certifire approved, making it suitable for FD30 and FD60 fire doors. To maintain the fire rating, it is essential to fit the appropriate intumescent pack, and a suitable door closer must also be installed.
