Product Details

GU Monolock Single Point Lock – 45/92, Silver (6-C4873-45-0-SS)

This GU Monolock single point mortise lock is designed for interior and exterior door applications. Part of the Europa Monolock series, this lock gear features a 1-3/4 inch (45mm) backset and 92mm PZ (handle to cylinder spacing), making it suitable for standard door configurations.

The lock operates with an American cylinder system requiring a 90-degree turn of the key or thumbturn. The deadbolt is positioned above the lever (US design), and the lever controls the release of both the deadbolt and latch. To lock the door, raise the handle, then use the key or thumbturn to secure the handles and keep the door locked.

This unit includes only the spring latch and deadbolt mechanisms. It cannot be used to repair a multipoint lock system and will not replace older lock cases with different configurations.
