Ladder

摘要

A safety device for mounting a ladder against a wall comprises an elongate aluminium box section main body (2) and a pair of aluminium box-section side arms (4) that extend transversely of the ends thereof to form a generally H-shape in plan. The longitudinal separation of the side arms can be varied by sliding, telescopic adjustment, and the side arms have sliding telescopic extensions to vary the spacing of the main body from the wall. The ladder is clamped by a rung to the main body of the device, which is fitted with gripping parts at all contact points. <IMAGE>
