Cylinder lock insert GERDA RIM E1 round — profile cylinder, GERDA MP WK RIM

GERDA RIM E1 round cylinder insert is a profile cylinder component designed to work with compatible rim lock housings. Supplied as a round insert, this cylinder core replaces or upgrades the locking mechanism in existing rim or surface-mounted locks. The component is intended for use where a replaceable profile cylinder is required to restore key control, change access, or refresh the lock without replacing the entire lock body.

Advantages

The round profile cylinder insert is manufactured to fit standard rim lock housings and provides straightforward replacement of the core. Its design allows rekeying or swapping cylinders quickly, reducing service time and avoiding full lock replacement. The insert is suitable for situations where maintaining the original lock case is preferred while updating the cylinder for security or access-management reasons.

Suitable for

• Replacement of worn or damaged cylinder cores in rim locks

How to use
