Abstract
Abstract For providing double gravity feed type shelving for use in conjunction with refrigerated article display units, a gravity feed shelf unit is provided and comprises a main chute structure arranged to be inclined so as to feed articles in the direction of inclination thereof and supplementary chute structure disposed alongside said main chute structure and similarly inclined so as to feed articles in the direction of inclination thereof, the supplementary chute structure being detachable so as to reduce the transverse dimension of the shelving structure if need be, the shelf units being specially adapted for interchangeable mounting one above the other whereby a single shelf in a refrigerated display unit is adapted for use as a double shelf display.
