Every year shock and vibration causes millions of dollars of damage during transport and handling of sensitive and valuable equipment. The Pelican SKID-MATE™ air-dampened cushions provide maximum protection against shock and vibration, taking the place of wood skid runners and permit four-way pallet entry, making loading and unloading easy. The Pelican SKID-MATE™ is designed to mount directly to pallet bases with a 5/16-18 UNC bolt. The SKID-MATE™ Spacer adds an additional 1-1/8 in to the SKID-MATE™ cushion, increasing the total height to 4 inches, allowing your pallet-loaded freight to accept most pallet jacks. Pelican™ SKID-MATE™ Pallet Air Cushion, 30 to 50 lb, Green, 6 in Dia, 4 in Height, Polyethylene, 5/16-18, -40 to 130 °F
