Abstract
A counter-balance weight for a modular safety rail comprises a substantially solid body which defines a passage to receive an end of an elongate spacer member, a recess region to house a retainer of a kind selectively securable to the elongate spacer member, an access opening for access to the retainer, and a retainer abutment to inhibit movement of the retainer in an axial direction which is parallel with the length direction of the elongate member.
