A. Ensure Child Safety: The window child lock restrictor is designed to restrict the opening distance of windows and doors, which may help reduce the risk of injury from falls. Meanwhile, it allows fresh air to flow. It is suitable for most wood, PVC, and aluminium hinged, sash, and sliding (horizontal or vertical) windows. It is a good choice to ensure the safety of your children or pets. B. Easy to Install: This cat window restrictor comes with strong adhesives. There is no need for drilling or screwing into the window frame. You can simply peel off the adhesive backing and attach it to the window. It also comes with spare adhesive tapes, so you may reuse it when you have new windows to avoid drilling near them. You can also install it using the included screws for added safety. C. Simple and Practical: It is designed with a 360 - degree swivel steel cable. So, no matter what side or angle you install the plates, the cable will swivel and hang down out of the way when unlocked. You can simply turn the key to open the lock, without having to awkwardly fumble with combination locks, misplace padlocks, or face issues because you forgot your number combination. Only one hand is needed to operate. (Keyed alike) D. Strong Sturdy Design: The refrigerator lock is made of a strong metal bullet - head and high - tensile steel cable, making it sturdy and durable. It has been tested to withstand a horizontal force of 100 kg. E. Wide Application: These childproof window locks are also suitable for many cabinets, drawers, and doors. They can also be used to hold down toilet seats and seal off the doors of microwaves, freezers, and other appliances. This helps ensure that your child can explore in a safe home environment. F.
