The Aluminum Sheave Housing Kit slides onto the flange of an aluminum cradle beam. Then the housing secures to the flange with the enclosed stainless steel 1/2 in. hex head bolts, 1/2 in. lock washers, and 1/2 in. nuts.
Made from 6061-T6 US aluminum. Features a no-weld design. The size of the web and flange determines which size housing you will need. All three sized housings include a 3 1/2 in. x 3/4 in. stainless steel axle bolt, 3/4 in. stainless steel lock washer, and 3/4 in. stainless steel nut.
The beam size is measured by the web height. 6 in. web (4 in. flange), 8 in. web (5 in. flange), and 10 in. web (6 in. flange).
