The Suspenz storage solution allows you to build a versatile rack to meet YOUR Free-Standing needs. Everything starts with a Free-Standing Frame. You add any of the Canoe, Kayak or Stand Up Paddle Boards (SUP) arm attachments to one side. And to make it a double-sided rack, you add a Back Leg. You can also make it a Rolling Rack with the Casters & Cross-Bar. YOU build your own Free-Standing storage rack!
