TSS Modern Deadlocking Nightlatch Case Only – 40mm Backset Narrow Stile Lock

The TSS Modern Deadlocking Nightlatch (Case Only) with 40mm Backset is a reliable and cost-effective security solution designed for residential front doors and narrow stile applications. Featuring a durable 5-pin cylinder deadlocking mechanism, this modern nightlatch provides enhanced security while maintaining ease of use for everyday access.

• 5-pin cylinder for dependable day-to-day security
• Deadlocking function prevents operation of the internal handle when locked

Enhanced Front Door Security

This deadlocking nightlatch automatically secures the door when closed, providing convenient protection for homes, flats, apartments, and residential properties. When operated with a key from the outside, the latch can be deadlocked, disabling the inside handle and helping to prevent unauthorised entry through letterboxes or broken glass panels.

Holdback Function

The integrated holdback feature allows the latch to be temporarily held in the open position, preventing the door from automatically locking. This can be useful where frequent access is required, although users should consider their individual security requirements when using this function.
