Abstract: There is a clamp for a universal beam (18). The clamp includes a flange hook (1) and locking plate (8) which are disposed on a support bar (2) for relative slidable adjustment over a range of beam configurations. In a position of use the clamp is attached to the beam (18) by slidable adjustment of the flange hook (1) and locking plate (8) to engage respective beam flanges (19, 20) in a manner to obtain a rigid load bearing beam mounting for the support bar (2).

Abstract: There is an anchor for securing a working line (54) to a structure. The anchor includes a sole plate (2) with an attachment (19) for the working line (54). There is at least one friction plate (5) and a connector strap (4). In use of the anchor the sole plate (2) and friction plate (5) are located against respective opposite sides of a rafter (3) of the structure and are linked together by the strap (4) in a manner such that the working line load on the sole plate (2) generates a clamping force between the sole plate (2) and the friction plate (5). This force resists movement of the anchor by gripping only the outside of the rafter (3).
