The slotted uprights comprise rectangular cross section tube and the slots are spaced to accept the hooked ends of the upper (6) and lower (5) clamping flanges. The flanges have grip jaws to grip panels (1) and one of each pair has its jaw (8) on threaded adjusters. The adjusters have guide pegs (10) through the jaws and simple tensioning screws (9). The clawed ends are secured by a clamping plate (17) with slotted profile to clip between the claws and the upright.
