The Shell Holder Rack has twelve positions that hold two shell holders on each post. There is also room to store six Trim Pro Shell Holders as well. The clear cover keeps out the dust and dirt while allowing you to see what is stored in the rack. The Shell Holder Rack can be mounted on the wall or used on the bench. The wall mount spacing allows it to be hung off of standard 1" pegboard hooks as well. The support legs angle the bottom out for wall mounting or the top up for bench use. Additional Shell Holder Racks can be snapped together if more shell holder storage is needed.
