In a cabinet having vertically extending side members (5) forming part of a chassis of the cabinet, panel mounts (1), also to extend vertically in the cabinet and to have panels mounted thereupon, are mountable to the side members (5) by integral members (3) which extend parallel to the outer face of the panel mount (1) at a spacing from the outer face and in a direction perpendicular to the longitudinal extent of the panel mount (1), i.e., horizontally. The integral members (3) are engaged in respective apertures in the side members (5) or in braces (7) extending between the side members (5) followed by forward or rearward movement to effect securement, retaining means such as pins or studs then being inserted in aligned bores (8, 9) in the panel mounts (1) and side members (5) to prevent return movement.
A method of securing in abutment two tubular metal members, comprising the steps of forming at least two first holes in one wall of each of the metal members, acting through the first holes so formed to burst second holes, respective to each of the first holes, in the opposite walls of the metal members to form outwardly-extending collars, screw threading the collar in one of the metal members, engaging the collars of the other of the metal members in the first hole of one of the metal members, and engaging threaded fasteners through respective ones of the aligned first and second holes in the metal members to engage the screw threads in the collar of the one of the metal members to clamp the metal members together.
