Window Tilt Latches

Window tilt latches are small locking mechanisms that secure a tilt-in sash on double-hung and single-hung windows while allowing the sash to release for easy cleaning. Replacing worn or broken tilt latches restores smooth operation, reduces drafts and rattling, and improves home security by keeping the upper corners of the sash firmly seated in the frame.

This hardware comes in surface-mount and internal (mortise) designs for vinyl, aluminum, and wood windows. Common materials include durable nylon or polycarbonate with stainless springs, and die-cast zinc for heavy-duty applications. You’ll find left- and right-hand latches, low-profile styles, and color-matched finishes such as white, black, beige, and bronze to blend with window frames. Many replacement tilt latches are sold as matched pairs for the top rail of a sash.

Choosing the right replacement tilt latch starts with accurate measurements. Note the body length and width, the distance between screw holes (center-to-center), the thickness of the sash rail, and the mortise depth for internal styles. Identify corner-mount versus side-mount layouts, handedness, and whether the original uses slide-in tabs or screw-fastened plates. Matching these details ensures a snug fit and a tight weather seal.

Quick installation tips:
- Work on a flat surface and support the glass.
- Photograph the original latch before removal.
- Replace both latches at the same time for balanced engagement.
- Use the correct screw length to avoid piercing the sash.
- Test the tilt function and lock-up before final tightening.

Regular inspection of window tilt latches prevents accidental sash drops and protects balances from strain. A simple screwdriver swap can revive a sticky sash, reduce energy loss, and extend the service life of double-hung windows.
