Winkhaus Tongue Multipoint Locks: One Motion Lock (OML) Systems

Winkhaus One Motion Lock (OML) tongue systems represent a specialized category of European multipoint hardware that combines convenience with security. These locks automatically retract all locking points—including tongue hooks and the deadbolt—when the interior handle is depressed, eliminating the need to turn a thumb turn before exiting. MPLocks maintains limited old stock of these Winkhaus tongue locks, and our team can help identify replacement options when original hardware is no longer available. Due to manufacturer discontinuation of many Winkhaus models, finding exact replacements requires careful attention to backset, PZ spacing, and faceplate dimensions.

Single-Motion Operation for Convenient Entry and Exit

The defining feature of Winkhaus OML tongue locks is their automatic retraction mechanism. When the handle is depressed, all locking points disengage simultaneously, allowing the door to open without additional steps. This design is particularly valuable for emergency egress situations and everyday convenience. The tongue-style locking points engage into corresponding strike plates in the door frame, creating multiple secure contact points along the door edge for enhanced resistance against forced entry attempts.

European-Style Backset and PZ Configurations

Winkhaus tongue locks are manufactured with specific European measurements that must be matched precisely when replacing existing hardware. Common configurations include 45mm (1-3/4 inch) and 60mm (2-3/8 inch) backsets, paired with the standard 92mm (3-5/8 inch) PZ spacing for euro profile cylinders. The faceplate width—either 16mm or 20mm—must also align with the mortise pocket in your door to ensure proper installation and operation.

Finding Replacements for Discontinued Winkhaus Hardware

Many Winkhaus tongue lock models have been discontinued, making direct replacements increasingly difficult to source. When searching for a replacement, measure your existing lock's backset from the faceplate edge to the cylinder center, and verify the PZ spacing between the handle spindle and cylinder centerlines. The overall faceplate length and handle height position are also critical for ensuring compatibility with your door preparation. In some cases, alternative multipoint lock systems from other European manufacturers may provide a compatible solution.
