The rectangular-tube cage, also called a rack cage, is designed specifically for beam-type pallet racking. A standard cage has stacking feet underneath; placing it directly on rack beams gives a small, unstable contact area. The rectangular-tube cage swaps those feet for rectangular tubes — a long bar that sits fully on the rack beam, spreading the load wide, seating firmly, and lifting off easily. These cages suit warehouses already on beam racks that want to sit cages directly on rack positions — merging cage and rack into one and skipping the pallet layer. When selecting, send us the rack-beam spacing together with the cage's outer dimensions; we match the rectangular-tube feet to your rack.
