The Union Window Restrictor Safety Lock is an essential security solution for homeowners, particularly those with young children, looking to prevent accidental falls or unauthorized entry. This device provides a crucial physical barrier that limits window opening while maintaining airflow, though it requires precise measurement and installation to ensure maximum effectiveness on your specific window frames.

The restrictor is primarily designed for side-hung or top-hung windows; compatibility with sliding windows depends on the frame design.
No, each restrictor typically comes with a matched set, so it is important to keep the keys in a safe, labeled location.
It serves as a secondary security measure to limit opening; it should not be considered a replacement for primary window locks.
It is specifically designed for uPVC and timber; installation on metal frames may require specialized drill bits and screws not included.
The opening distance is determined by the length of the cable and where you choose to mount the brackets on the frame.
Apply a small amount of silicone-based lubricant to the keyway and ensure the cable is not under tension when attempting to unlock.
Check that the base plates are securely fastened to the window frame and the mounting screws are fully tightened.
Before installation, verify that your window frame has sufficient flat surface area to accommodate the base plates. Use a measuring tape to determine the optimal placement that allows for desired ventilation while ensuring the window cannot be opened wide enough for a person or pet to pass through. Always use the provided screws and ensure they are driven into a solid part of the frame. For care, wipe the cable and locking mechanism occasionally with a soft, damp cloth to remove dust or debris, and apply a small amount of light machine oil to the lock cylinder annually to keep the mechanism operating smoothly.
