Ensure Child/Pet Safety: This window restrictor is designed to limit the opening distance of windows and doors, reducing the risk of falls. It still allows fresh air to circulate. Suitable for most windows made of wood, PVC, and aluminum, including casement and sliding windows (horizontal or vertical). The smaller pad size of 4.2cm width ensures it fits most UK window frames. An ideal choice for ensuring the safety of your children or pets. Easy to Install: This cat window lock comes with strong adhesive, requiring no drilling into the window frame. Simply peel off the adhesive tape and attach it to the window. It comes with spare adhesive tape so we can reuse it when the new windows are in place to avoid drilling near the new windows. You can also install it with the included screws for added security. Warm tips: Measure before purchasing. The width of the window frame should be less than 4.2cm/1.6in, otherwise the lock will overhang the edge of the frame. Simple and Practical: Designed with a 360° rotating steel cable, so no matter which side or angle you install the plates, the cable will swing and hang out of the way when unlocked. Simply turn the key to open the lock – no fumbling with combination locks, lost padlocks, or going hungry because you forgot your number combination! Only one hand is needed to operate. (Same keys) Strong and Robust Design: The refrigerator lock is made of a strong metal head and a steel wire rope, making it more robust and durable. Tested to withstand a horizontal force of 100 kg. Wide Range of Uses: These child safety window locks are also suitable for many cabinets, drawers, and doors. They can also be used to hold down toilet seats and seal the doors of microwave ovens, freezers, and other appliances. This ensures that your child can explore in a safe home environment.
