The flange includes a circular opening 14 having a slot extending therefrom to enable the flange to flex so that the tray may be engaged with a pipe, the pipe being received in the opening. The slot may include a stepped portion 15 that is approximately equal in thickness to the flange. A portion 16 of the wall adjacent the slot may include a rib 17 and a channel 18 on opposing sides of the slot, wherein the channel and rib may be secured to one another once the tray is engaged with the pipe, so as to secure the pipe within the tray. The tray may be square or triangular in plan, with each corner of having a rebate and associated circular opening and slot. The respective circular openings may be of different sizes so that the device is suitable for use with a varying range of pipe bores.
