The mechanism re-engages and locks automatically as soon as the window is closed — no manual re-setting required. The 100 mm restriction is active by default on the next opening, and only releases when the key is turned.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv style=\"margin-bottom:14px;\"\u003e\r\n\u003cp style=\"margin:0 0 4px 0;color:#1B365D;font-weight:bold;\"\u003eHow far does the window open with the restrictor fitted?\u003c\/p\u003e\r\n\u003cp style=\"margin:0;\"\u003eApproximately 100 mm. This is the most widely-referenced opening figure in UK fall-prevention guidance for occupied buildings, and is sufficient to provide ventilation while preventing a child from passing through the gap.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv style=\"margin-bottom:14px;\"\u003e\r\n\u003cp style=\"margin:0 0 4px 0;color:#1B365D;font-weight:bold;\"\u003eAre screws included?\u003c\/p\u003e\r\n\u003cp style=\"margin:0;\"\u003eNo — we recommend 4 mm (No.8) countersunk head screws sized to suit your frame. This is so installers can match screw length and material to their specific frame type and substrate.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv style=\"margin-bottom:14px;\"\u003e\r\n\u003cp style=\"margin:0 0 4px 0;color:#1B365D;font-weight:bold;\"\u003eCan I retrofit this to existing windows?\u003c\/p\u003e\r\n\u003cp style=\"margin:0;\"\u003eYes.

It is an opening-restriction safety device, not a guard.
