Abstract: Carriers adapted to support strand spools in wire type pallets are disclosed. Each carrier comprises a tray having gripping devices or claws for centering the carrier at the intersection of the crossed support wires which comprise the pallet. Tubular supports extending upwardly and downwardly from the central tray are adapted to hold the ends of spools in position on stacked pallets. The lower support is slotted so that it can extend beneath the plane of the pallet. A central bore extending through the supports and the spool tray allows for circulation of air and treatment fluid so that the spools may be treated with steam or other treatment gas while on the pallets.
