GU Monolock 30/92, Stainless Steel (6-C4873-30-0-SS)

The GU Monolock is a single point mortise lock system designed for both interior and exterior door applications. This Europa series lock features a 30mm backset and 92mm PZ (handle to cylinder spacing), making it suitable for doors requiring a compact backset configuration.

This lock operates with an American cylinder system using a 90-degree turn of the key or thumbturn. The key position is located below the handle in the Europa configuration. To lock the door, lift the handle to extend the deadbolt, then use the key or thumbturn to secure it in place.

The Monolock shares the same routing and mortising dimensions as GU multi-point locking systems, allowing for consistent installation across different lock types. The heavy-duty mortise construction includes a reinforced lever return spring system for reliable long-term operation.
