The Hsthe Sea Window Restrictor Locks are an ideal safety solution for parents, property managers, and facility owners looking to secure windows in homes, schools, and offices. These locks provide a critical safety barrier by limiting window opening distances to between 11 and 16cm, ensuring fresh air circulation while preventing accidental falls; however, users should note that they require precise drilling for proper installation and the key must be stored securely to maintain safety.

These locks are designed for UPVC, wood, aluminum, and metal frames.
Yes, each kit comes with the security cable, mounting plates, keys, and self-drilling screws.
Use the provided key to unlock the cable from the window sash bracket, which allows the window to open freely.
The cable limits the window opening to between 11cm and 16cm.
Yes, they are suitable for schools, hospitals, and commercial offices where window safety is a regulation or necessity.
Ensure no paint or debris has entered the lock mechanism and try applying a small amount of dry lubricant.
Re-adjust the mounting position of the cable base plates further or closer to the window pivot point to calibrate the opening range.
Installation requires only a screwdriver or a power drill. 1. Determine the optimal placement on the window frame and the opening sash. 2. Align the mounting plates and mark the hole positions. 3. Use the included self-drilling screws to secure the plates firmly into the frame material. 4. Test the cable length by attempting to open the window to ensure it meets the 11-16cm restriction range. For care, keep the lock mechanism free of dust or paint buildup to ensure the key turns smoothly. Periodically inspect the cable and screws for any signs of loosening due to frequent window movement.
