Winkhaus OML Hook Multipoint Locks — One Motion Hook Locks for Doors

Winkhaus OML Hook Lock Replacements and Conversion Kits

The Winkhaus One Motion Lock represented an innovative approach to multipoint security, combining hook-style locking points with convenient single-motion operation. While these original OML systems have been discontinued by the manufacturer, MPLocks maintains expertise in helping homeowners and contractors find suitable replacement solutions. Whether you have a single door or double French door configuration, understanding your existing lock's specifications—including backset (35mm, 45mm, or 60mm), faceplate width (16mm or 20mm), and door height—is essential for selecting the correct replacement kit.

Understanding Winkhaus OML Hook Lock Configurations

Winkhaus OML hook locks were designed with the key positioned above the lever handle, a distinctive feature that set them apart from many other multipoint systems. The hook locking points engage into strike plates mounted in the door frame, providing superior resistance against forced entry compared to single-point deadbolts. When reviewing replacement options, you may encounter part numbers like 20/60/92, which indicate a 20mm faceplate, 60mm backset, and 92mm handle spacing (PZ measurement). These specifications must match your door's existing cutouts for proper installation.

Replacement Solutions for Discontinued Winkhaus Locks

Since original Winkhaus OML components are no longer manufactured, MPLocks offers custom replacement kits that restore multipoint functionality to your door. Some conversion kits may reposition the key below the lever, slightly changing the handle height from the original 36-inch position. These kits are available for various door heights, from standard 6 foot 8 inch residential doors to taller 8-foot configurations, and include options for both single door and double door applications with active and passive panels.

Measuring Your Winkhaus Door for Replacement Parts

Accurate measurements are critical when ordering Winkhaus OML replacement components. Start by measuring your backset—the distance from the edge of the door to the center of the cylinder keyhole—which will be either 1-3/8 inch (35mm), 1-3/4 inch (45mm), or 2-3/8 inch (60mm). Next, measure the faceplate width on the door edge, typically 5/8 inch (16mm) or 25/32 inch (20mm). Finally, note your total door height in inches, as hook positions vary based on panel size. Bottom hooks on OML systems are typically positioned at 27.2 inches (691mm) from the door bottom.
