The DELTANA WL07U5 is a window sash lock designed to secure single- and double-hung window sashes in residential and light commercial applications. Measuring 15/16 inches by 2-5/8 inches, this compact hardware unit provides a positive latch engagement between meeting rails. The antique brass finish delivers a traditional aesthetic suited to period-style millwork and interior trim packages. Weighing 0.2 pounds, the WL07U5 is a lightweight, direct-mount unit typically installed by carpenters, window installers, or general contractors during new construction or window replacement projects.
The WL07U5 fits standard wood and vinyl double-hung window frames where a cam-style or sweep sash lock is required at the meeting rail. It is sold individually and suits both new installation and hardware replacement on existing window assemblies. The antique brass finish coordinates with matching DELTANA door and window hardware lines for consistent trim packages throughout a project.
Designed as an OEM-style replacement or new-installation sash lock for standard single- and double-hung window assemblies where a meeting-rail cam lock is required.
Installation is typically performed by a carpenter or window installer using a drill and standard screwdriver bits. Mark and pre-drill pilot holes at the meeting rail to avoid splitting the sash material before fastening. Confirm sash alignment before final tightening to ensure the lock engages cleanly without binding. No specialized tools or licensed trade credentials are required for standard residential window hardware installation.
