KEEP YOUR CHILD/PET SAFE: The window locks are designed to limit how much doors and windows can be opened, reducing the risk of fall injuries. At the same time, fresh air can flow in. Suitable for most inward-opening, tilt-and-turn, and sliding windows (horizontal or vertical) made of wood, PVC, and aluminum. The smaller pad size of 4.2 cm wide ensures it fits most UK window frames. Perfect for protecting your children or pets. Easy to install: This cat window restrictor comes with a strong adhesive, you don't need to drill holes in the window frame, just peel off the adhesive backing and stick it to the window. It comes with extra tape so we can reuse it on the new windows and save time drilling holes near the new windows. You can also install it with the included screws for double security. Important tips: Measure before buying. The width of the window frame should be less than 4.2 cm, otherwise the lock will protrude beyond the edge of the window frame. Simple and convenient: Designed with a 360° swivel cable to prevent it from rolling. No matter which side or angle you mount the panel on, the cable will twist and hang down when unlocked.
