Specifications: Rubber slurry is made of high-quality rubber. The thick rubber paddle measures 1.9 inches W x 4.9 inches L, with a minimum tensile strength of 725 PSI (5 MPa). The metal band measures approximately 1.3 inches W x 3.7 inches L. Hex bolts are 5/16-18 x 1 inch coarse threaded, with matching 5/16-18 locking nuts (install using a 1/2 inch wrench and socket). The package includes 9 self-locking screws, all made of high-quality metal. Function: This snow blower impeller conversion kit reduces the gap between the snow blower’s impeller blades and the impeller chamber wall. A smaller gap increases operating efficiency and snow-throwing capacity, and reduces the likelihood of snow clogging.
