The BabyDan Window and Door lock restricts the opening of a window or door to a maximum of 15cm. Featuring a 20cm steel plastic coated cable, the modern design doesn’t draw attention or affect the aesthetics of your window. It comes with a key, which means that the locking mechanism cannot be unlocked or removed without the key holder’s knowledge. Made from solid stainless steel, the restrictor is completely tamper proof. Tested to the full safety standard EN13126-5 (Force up to 550kg).
