Strong, general use steel sheaved pulleys for applications with wire rope. 2-3/8" x 5/8" (60 x 16 mm) single pulley with a becket, steel sheave, stainless steel side plates and a sealed needle bearing, Top hole will accept two carabiners and has a bottom becket to simplify block and tackle systems. Bearings decrease the amount of surface area in contact with the axle, which creates a more efficient transfer. By rolling the load around the axle, load on the transfer point is increased, which results in faster wear, shortening the life of the pulley. Min. breaking strength 9,500 lbf. (42.25 kN). Weight 15.5 oz. (439 g). Made in the U.S.A.
