Window Hardware

Complete window hardware covers not just the fastener that closes the window, but the stay that holds it open at a chosen angle, the lift that provides a grip for operating the sash, and the security fittings that prevent unauthorised entry. At the DIY Hardware Store, our broad window hardware range covers the casement stays, casement fasteners, sash lifts, sash fasteners, and security restrictors used across standard UK timber window installations.

The casement stay - the slotted arm that holds a casement window open at a controlled angle - is one of the most frequently worn fittings on older properties. The pin that locates in the stay slot wears through the slot over years of use, eventually allowing the stay to slip and the window to blow shut in wind. Replacement is straightforward, and matching the stay and pin finish to the casement fastener creates a coordinated, professional result. Sash window hardware including lifts, pulleys, sash cord, and fasteners complete the picture for traditional double-hung timber windows.
