A cable ladder comprises side rails (10) and two types of strut (20, 36) whose ends interfit with the side rails. By using a combination of struts, one type (20) with angled extension (32) and the other type (36) with linear extensions, which extensions extend through apertures (18) of the side rails, a cable ladder can be constructed requiring no additional fixing such as welding or rivets. <IMAGE> |
