The potentially dangerous conventional bolt retaining clip on the bottom plate has been dispensed with. A patented square shank bolt is fixed into the bottom plate, this feature makes it a very safe product. Fasteners are supplied with 8.8 Hi-Tensile bolts and nuts to ensure high torque ability which provides a better belt joint. All sharp edges are removed to prevent injury during handling. Back and front radiuses of both top and bottom plates are chamfered to ensure scraper friendly fasteners.
