High-Quality Material: The sliding window lock is made of aluminum alloy. The window locks are thickened, wear-resistant, durable, and sturdy. Before ordering a child-safe window lock for pets, please ensure your window tracks are higher than 0.6 inches/1.5 cm and wider than 0.63 inches/1.6 cm.

Packaging Information: You will receive 4 sets of sliding window and door locks, which include 4 door and window lock blocks, 4 hex wrenches, 4 protective washers, and 1 vertical key. These sliding door locks with a key can meet your needs.

Protective Washers: Each sliding window lock is equipped with a plastic protective washer to prevent scratching the window when turning the stainless steel screws on the window track. The protective washers can provide friction between the window lock and the track to ensure the window does not slide.

Easy Installation: The window lock is suitable for sliding windows and doors. Place the protective pad in place to avoid scratching the window, place the window lock in position, and turn the key to secure the window lock. Remember to take care of the keys.

Security: Window locks prevent children or pets from accidentally opening windows and avoid accidents. Window locks also protect against thieves. Multiple window locks can be attached together for increased security if needed.
