Abstract: A post for supporting upper and lower temporary guard-rail chains around the periphery of a concrete floor slab on a building under construction. The post has two vertically spaced pairs of hooks to which respective chains may be attached so as to make it virtually impossible to dislodge either chain accidentally. The post has a screw-threaded rod for insertion in a wire nut embedded in the floor slab. A clamping nut on this rod is adjustable to clamp the post in a position in which the hooks are on the side of the post away from the periphery of the floor slab.
