Invisible when not in use. It keeps the door or staircase 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 casing holds the mesh, protects it from dirt and damage, and gives the KiddyGuard Avant an attractive, elegant design. Suitable for openings up to 120 cm. Mounting materials for attachment to wood, brick, or concrete walls are included. The following tools are required: screwdriver, drill, and measuring tape. The KiddyGuard Avant remains locked in both the open and closed positions, so children cannot use it as a toy. Please install the gate first. Only then can it be unrolled.
