Window & Door Security

Windows and doors are the primary points of entry for opportunistic burglars - and improving their security doesn't require expensive systems. At the DIY Hardware Store, our window and door security range covers the practical, affordable security fittings that make windows and doors significantly more resistant to forced entry: window restrictors, sash jammers, hinge bolts, and window staylocks for domestic properties.

A window restrictor limits how far a window can be opened, preventing a person from climbing through while still allowing ventilation - essential for children's bedrooms and any room above ground floor level. Sash jammers lock a sash window in the closed position by jamming the sash against the frame, resisting the levering action used to force sash windows. Steel hinge bolts are concealed bolts fitted to a door's hinge side that lock the door to the frame and prevent it from being forced by levering at the hinge, even if the hinges themselves are removed.
