ABSTRACT:
A counter-balance weight for a modular safety rail includes a solid body of a compact shape which defines a substantially planar major surface which, in use, is intended to rest on a support surface The body defines a substantially linear through-bore for receiving an end of a spacer member. The through-bore extends continuously through the body in a direction substantially parallel with the substantially planar major surface of the body. The through-bore extends between a pair of end faces which, at least in part, are non-parallel end faces and the body further defines a screw-threaded aperture which extends through the body to intersect and communicate with the through-bore. The body may have a substantially triangular shape in transverse cross-section.
