Restore window security and improve performance with this Prime-Line Aluminum Window Sash Lock, designed for use on vertical and horizontal sliding aluminum-framed windows. Ideal for replacing worn, loose, or missing locks, this hardware upgrade helps ensure your windows close securely while maintaining proper alignment and function.
This sash lock features a cam-action locking mechanism that mounts directly to the checkrail of the inner sash and engages with the outer sash—eliminating the need for a separate keeper. This design simplifies installation while providing a tight, secure hold that helps reduce air gaps, improve insulation, and enhance overall window security.
Compatible with single-hung, double-hung, and some horizontal sliding windows, this lock offers versatile application across many aluminum window styles. The design accommodates both movable and fixed sash configurations, helping restore reliable operation in a wide range of setups.
Constructed from durable diecast zinc, this sash lock is built for long-lasting performance. The almond painted finish resists corrosion and blends easily with most window frames, maintaining a clean, consistent appearance throughout your home. The lock can be installed individually or in pairs depending on window size and support needs.
Installation is quick and easy with a standard Phillips screwdriver, and all necessary fasteners are included. With 2-1/4 inch mounting hole centers and a 1/2 inch latch projection, it’s important to compare dimensions with your existing hardware to ensure proper fit before purchasing.
