A counter-balance weight (20) for a modular safety rail comprises substantially only a solid body of a compact shape, wherein the volume of the material of said body is at least 20% of the volume of the smallest cuboid which is able to contain said body, said body defining a through-bore (21) for receiving an end of a spacer member (42) and said body further defining a screw-threaded aperture (31) which extends through the body to communicate with said through-bore. The body may be of a substantially triangular shape, such as that of an isosceles triangle, as considered in transverse cross-section in a plane substantially perpendicular to the longitudinal axis of the through-bore (21) and may have truncated edge regions (24,25). <IMAGE> |
