If you've already got RAD hook plates installed and just need to replace a worn strap or add another tie-down point, this Single Strap is an easy solution. Instead of purchasing another complete kit, you get one DOT-certified auto-retracting strap with upgraded orange tabs and all the necessary mounting hardware. It features a 1" x 9' strap length, a 1,200 lb assembly break strength, and a 400 lb working load limit. Please note that hook plates are not included with this product. This strap is designed to work with existing RAD hook plates and compatible pre-threaded mounting locations. It fits Ford F-150, F-250, F-350, and F-450 trucks. It can also be used with a Universal Kit for trailers and other custom applications. Some trucks may require tapping the bedside mounting holes with an M6x1.0 tap if factory threads are not already present. Each strap is hand assembled in the USA and includes hardened 10mm hex head bolts with a phosphate coating to help resist rust and corrosion for long-lasting use. Important Note: This strap requires existing pre-threaded bedside mounting holes or compatible BoxLink mounts. If your truck does not have threaded holes, they may need to be tapped with an M6x1.0 tap. Included 10mm hex head bolts are phosphate-coated for corrosion resistance, though some discoloration may occur over time.
