Sash Window Fasteners

The sash window fastener is the catch that holds the upper and lower sashes of a traditional double-hung sash window in the closed position, providing both a positive closure and a degree of security against casual entry. At the DIY Hardware Store, our sash window fasteners range covers the Brighton, fitch, and quadrant stay types used on standard timber sash windows in period and traditional UK properties.

The most widely used sash fastener is the fitch catch - a cam-operated lever mechanism that engages a keep on the opposing sash, drawing the two sashes together and holding them firmly closed. The Brighton fastener is a simpler version with a rotating arm that drops into a keep. Both create a positive closure that prevents the window from rattling in draughts and resists casual opening, though neither provides a high-security lock without an additional sash bolt.

Quadrant stays limit the opening angle of a casement sash and hold it open at a safe position, preventing the window from swinging wide in wind. Sash lifts provide a pull point for raising the lower sash. All available in polished brass, satin chrome, and antique finishes at the DIY Hardware Store.
