Product Details: The Rear Anti-Sail Tarp Tension Bow Set from Buyers Products prevents flapping and keeps your tarp in place at the rear of the bed or trailer. It's ideal for pull-style or manual crank-style tarp systems, adding weight and stiffness for ease of securing the tarp. It fits into the rear pocket of the tarp sleeve. The kits feature adjustable collars for correct positioning of the tarp. Choose from aluminum or powder-coated steel construction. Available in lengths of 91", 96", 98", and 102". Steel is also available with rollers (DTB102) for smooth extension and retraction.
