Hauser produces aluminum of the highest quality aluminum. Our tubular product is made from high quality aluminum that is up to 30% thicker than the metals used in many other products on the market. This adds to superior strength and longevity to our product. Hauser sling products are stretched and inserted into a specially developed extrusion with the use of a nylon cord to secure them in place. The sling is then attached to the frame using nylon washers and stainless steel bolts. Hauser recommends storing tubular product in a sheltered area over the winter months to prevent moisture getting trapped inside the extrusion and freezing.
