There is a whole world happening right beyond your home that can entice your children to the window. That's why Dreambaby® created the Breezz-Guard® Keyless Window Restrictor. It helps prevent children from opening the window beyond a safe distance, reducing the risks of falls. This latch is great for windows all throughout your home. They can be used on aluminum, wood or plastic frames and is suitable for sliding, sash, and outward/inward opening windows accommodating most homes. The Breezz-Guard® allows you to open the window and enjoy the weather while knowing your family is safer. The locking mechanism is simple, just insert the cable head and slide it into the locked position. When it's time to clean the windows, it can be easily disengaged by an adult. You will install the Dreambaby Breezz-Guard® so it limits the window opening to 4 inc (10 cm) at its widest point. The easy to follow instructions are enclosed in your pack.
