Our conveyors have standard overall widths 'A' of 300mm - 450mm and 600mm and lengths 'B' of 1500 and 3000mm. Sizes other than standard are manufactured to order and attract a small price premium. Frame holes are punched @ 38mm intervals so that rollers can be pitched at 38, 75, 112 and 160mm pitch etc. Frames are supplied with a hook and keeper that allows them to be joined quickly and easily.
