Shipping tube is needed to ship extrusion trim to protect against damage. It will be pvc or a heavy cardboard tube. You are not paying $15.00 just for the tube. The $15.00 also covers the additional cost UPS/FedEx charges for shipping items in a tube. This $15.00 does not cover the actual shipping charges of the products.
If you are ordering any of our extruded aluminum products, you must order this item to have your products shipped in. Order only 1 tube regardless of the number of extrusions you order.
