1,243,771. Ladders. D. H. MATTHEWS. 18 Oct., 1968 [21 July, 1967], No. 33561/67. Heading E1S. A metal extension ladder has tubular stiles, e.g. A, each formed from a channel-sectioned member 3 and a closure member 1, the ends of the channel-sectioned members each being formed to a hook shape to engage corresponding formations on the adjacent stiles. In the embodiment of Fig. 2, not shown, the channel-sectioned members (20) have diverging sides terminating in C-section edges.
