Adjustable Window Safety Lock

Add a practical way to control how far a compatible sliding window can open. The adjustable safety lock attaches to the window track and acts as a stop, allowing limited ventilation while helping restrict the window from opening fully—particularly useful in homes with children or pets.

Sliding windows may open farther than intended, creating concern in homes with children or pets and making it difficult to maintain a limited ventilation gap.

The lock is secured to the compatible window track at the selected position, where it acts as a physical stop that limits movement and helps maintain the desired opening distance.

The product appears designed for sliding-window tracks whose edge can fit inside the metal channel. Although it may suit several common window designs, compatibility depends on the track’s shape, thickness and available installation space.

It offers a simple, adjustable way to control the window opening distance. It can also be removed or repositioned without a complicated installation system, provided that the window track is compatible.
