S-Cargo Truck Caps is pleased to offer racks from Colminn-X Racks! Colminn-X racks are custom built in Colorado. Working with a local provider allows us to accomodate special requests and custom features to get you the rack that will work best for your needs. Colminn-X racks feature a welded construction that is much stronger than generic bolt-together rack options on the market. Colminn-X Racks can be built to work with your fiberglass or aluminum topper, tool boxes, or tonneau covers. Whether you are looking for a pipe rack, lumber rack, ladder rack, or something completely custom, we can get the perfect rack for you.
