The Mega Stacking Hand Gun Racking System accommodates 8 guns in a heavy duty rack constructed of 3/4" tubular steel and heavy, vinyl coated steel wire. Each set is supplied with 4 couplings so that 2 or 3 racks can be stacked one on top of the other to allow maximum density and utilization of storage space. Quickly assemble with a #2 Phillips screwdriver.
