Sturdi-Bilt style pallet racking has slots on the corners of the upright column and has a unique beam connector that requires a flat metal beam clip on which the beam hangs on. Our slotted style rack is compatible with other Sturdi-Bilt rack styles. This is a good roll-formed rack that provides the same capacities as other roll-formed styles of racking but must use beams that have the Sturdibilt style connector and beam clips. It's the right solution for applications where existing rack is of the same type.
