The Codelocks CL255 is a light-duty mechanical push-button lock designed for controlled access on internal and external doors. This model features a dual backplate and a mortice latch, providing a reliable security solution for environments such as offices, storerooms, and staff areas. The integrated key override facility is particularly useful for cleaning staff or security personnel, allowing immediate access without the need for the code.

The spring-loaded latch ensures the door locks automatically upon closing, while the deadlocking plunger provides an essential security feature by preventing the latch from being shimmed or forced. For periods where unrestricted access is required, the lock includes a slide button to hold the latchbolt open. This passage mode function can be permanently disabled during installation if a code is required for every entry.

Typical applications include:

  • Internal office doors requiring restricted access
  • External storage units and sheds
  • Residential properties needing keyless entry with a mechanical backup

This mechanical lock is a self-contained unit that operates without the need for batteries or electrical wiring. It supports 4 to 6-digit codes and is designed for straightforward installation. Its reversible handing makes it a versatile choice for a wide range of door configurations.
