The Topper “Knock-Down” rack is the same Topper rack, with the same strength and durability you expect. The difference is it give us and our dealers the ability to ship our racks via UPS. The Knock-Down rack refers to the breakdown of the rack. It means that the side rails are each two separate pieces that are joined together in the center with a zinc plated bushing and galvanized splice plate. We also added supports in the center on each side where the side rails are joined together, insuring your maximum 750 lb. payload capacity.
Having the ability to ship our products through UPS allows us, and our dealers, to continue to offer our customers the strongest, most durable rack on the market at a fraction of the cost.
