The ERA replacement rim cylinder is a core security component designed to provide keyed access for doors fitted with surface-mounted night latches. As a 5-pin mechanism, it offers a reliable level of security for residential and light commercial applications. The cylinder functions by transferring the rotational movement of the key through a flat metal tailpiece into the internal lock case, allowing the latch bolt to be retracted from the outside.

Typically used during maintenance or security upgrades, this component is the ideal choice when original keys have been compromised or when a property changes hands. It allows for a complete change of locking combination without the cost or labour involved in replacing the internal latch assembly. The unit is designed to fit through a standard 32mm hole, making it a universal fit for most traditional rim lock installations on timber doors.

  • Application: Suitable for timber doors where a night latch is present.
  • Installation: The adjustable tailpiece can be trimmed to size, ensuring the cylinder sits flush and functions correctly regardless of the door thickness.
  • System Role: Functions as the external keyed interface for rim-mounted locking systems.

When installing, it is essential to ensure the tailpiece is correctly aligned with the internal latch mechanism to prevent friction or binding during operation. Periodic lubrication with a graphite-based lubricant is recommended to maintain smooth key entry and rotation.
