Abstract: A method of fixing a tubular metal member in an aperture which comprises, locating the tubular metal member in the aperture and deforming the 10 metal of the tubular member to expand to extend within the confines of said aperture, which may be formed in masonry. A method of fixing two tubular metal members one to the other, is disclosed, which comprises locating a first tubular metal member (10) through a transverse aperture (12) in a second tubular metal member (11) and deforming the metal of the first member (10) to expand (13) to extend within the longitudinal passage of the second member (11) at the location of the transverse aperture (12) therethrough. A tool for carrying out the method is also disclosed.

Abstract: A combined mounting and blanking spigot for providing fixing between a rectangular cross-section tubular rail and a post, comprising a solid member having a height and width slightly less than that of the interior dimensions of the rail and a length sufficient to blank a gap between the rail and post. One end surface is planar for attachment to the post and one side surface is planar, the other end and other side surfaces being formed to be arcuate or cut away at their adjacent corner. An aperture is formed vertically through the spigot at substantially the midpoint of the upper surface area thereof. A railing unit having at least two rails attached to a post by the spigots is also disclosed.
