Deal Rite Tent and canopy side walls are made with the best materials available and use only quality hardware and fittings. Seams are 1 1/4" overlap heat welded for durability and long life. All walls are labeled as fire retardant. All walls are two feet longer than stated size to accommodate a one foot overlap at each end. Overlaps are secured together with three quick release snap buckles. The walls hang on metal (plastic available) snap hooks which are attached every 30" on top. 5" heavy duty wind straps are attached at the bottom for staking. Other colors and blockout are available in our 1st quality curtains for a slightly higher charge. Call us with your custom sidewall needs.
