A hand-rail element has a metal pipe core, which is easily bent, and a soft plastic foam surrounding the pipe and having an outer surface contoured to simulate leather graining or the like. Several elements can be joined end-to-end by means of threaded nipples, and a hand-rail support is also disclosed, which permits assembly of these parts by a worker who need only use a portable power drill for on-site installation. |
