A fastener (fitch or Brighton catch) where the sashes meet, sash lifts for raising the lower sash, and optionally sash stops or travel restrictors for security and child safety. All fit with basic tools to timber sashes.
Fit sash stops or dual screws so the sashes can't slide past a set point even if the fastener is slipped — the classic sash weakness. Key-locking fasteners add insurance-friendly locking at the meeting rail.
Fasteners fit the meeting rails of most timber sashes; check the rail width and existing screw positions. Brighton catches suit deeper rails, fitch catches suit standard ones.
