Types of Window Latches and Their Operation

Windows with latches come in various styles, each designed to secure the window while allowing easy operation. Understanding the type of latch installed is crucial for opening the window efficiently and safely.

Casement window latches typically consist of a handle that turns or a lever that lifts to release the locking mechanism. These latches are often mounted on the side of the window frame, securing the sash tightly when closed. To open, the handle is usually rotated or lifted, disengaging the latch from the catch.

Sliding window latches are generally smaller and may include a hook or a sliding bolt. These latches lock the window sash in place by engaging a notch or frame groove. To open the window, the latch is lifted or slid away from the locked position, allowing the sash to slide horizontally.

Double-hung window latches often feature cam locks or sash locks positioned at the meeting rail where the upper and lower sashes overlap. Releasing the latch involves rotating or lifting the cam, which unlocks the sashes, enabling them to be moved up or down.

Awning and hopper windows utilize latch mechanisms that pivot or swing the sash outward or inward. These latches often have a lever or knob that must be turned or pulled to unlock the window before pushing or pulling the sash open.
