Invisible when not in use. It keeps the door or stairs clear. When opened, no part of the KiddyGuard Avant will be in the way. No bottom threshold means no tripping hazard in the opening. Easy to operate with one hand, for example when carrying your child. Fits beautifully in both classic and modern homes. The aluminum housing holds the net, protecting it from dirt and damage while giving the KiddyGuard Avant an attractive, elegant design. Suitable for openings up to 120 cm. Mounting materials for attachment to wooden, brick, or concrete walls are included. The following tools are required: screwdriver, drill, and measuring tape. The KiddyGuard Avant remains locked in both open and closed positions, preventing children from using it as a toy. Please install the gate first. Only then can it be rolled out!.
