The grating (18) is held steady by an encircling frame (20) fixed to the two side posts (10) and the top (12) and bottom (14) sheets are held to the posts by plugs in the form of pins (28) which engage channels formed by the suitably shaped rightangled ends of the two sheets. The vertical legs of the grating frame adjoin fixer straps secured to the side post, the legs being screwed releasably to the post straps.
