ABSTRACT:
A counter-balance weight for a modular safety rail comprises substantially only a solid body of a compact shape wherein the volume of the material of the body is at least 20% of the volume of the smallest cuboid which is able to contain the body, the body defining a through-bore for receiving an end of a spacer member and the body further defining a screw-threaded aperture which extends through the body to communicate with said through-bore. The body may have a substantially triangular shape in transverse cross-section.
