Hyskore Double Stack Pistol Magazine Rack And Organizer Black. It is constructed from closed cell foam with a retaining lip that keeps the magazines in place and has a rigid extruded vinyl integral shelf that is angled to match the base angle of most magazines. It is strong enough to hold fully loaded magazines. The outer most set of mounting holes are exactly 16in apart to facilitate mounting directly to studs. The shelf can easily support the fully loaded magazines but the weight bearing capacity is ultimately a function of how it is mounted. It is therefore important to make sure that anchoring screws are firmly seated in appropriate wood members. As an added benefit each 19in foam set of foam storage points has die cut slots separating various segments to facilitate the separation of segments so that if for instance you have a 30316 rack which accommodates Glock style double stack magazines and a 30318 rack which accommodates single stack Colt 1911 style magazines you could actually mix and match segments so you can store both double stack magazines and single stack magazines on the same rack.
