Abstract: A supporting element for use in supporting ducting, particularly air ducting used in air-conditioning installations, comprises a metal strip shaped with transverse bends. The metal strip has a first minor extent of its length formed as curved bearing surfaces spaced around an arc at least approximately conforming to a semi-circle and a second minor extent of its length formed as fastening flanges extending radially outwards of said semi-circle substantially at the diametrically opposed ends of the arc. In use a pair of such elements are arranged in opposed relationship on opposite sides of a ducting having rounded lateral sides with tie-rods connecting the opposed fastening flanges. It is preferred that isolating pads of heat and/or sound insulating material are provided on each said bearing surface.

Abstract: A method of supporting rectangular-sectioned ducting according to which the ducting is supported at each of a number of spaced positions along its length by means of a pair of opposed angle elements in which the ducting is directly or indirectly seated at its lower corner edges, the angle elements being secured together by means of a tie rod extending beneath the bottom wall of the ducting and being suspended from drop rods.
