2-3/8" x 5/8" (60 x 16 mm) single pulley with becket that features an aluminum sheave, stainless steel sideplates and a bronze bushing. A bushing spreads the load over a larger area of the axle, sliding the load around the pulley. This results in greater transfer and very little wear and longer life. However, the greater area in contact results in increased friction, decreasing efficiency. Features swing side cheeks and the top hole will accept two carabiners. Bottom becket simplifies block and tackle systems. Min. breaking strength 9,5000 lbf. (42.25 kN). Weight 11 oz. (311 g). Made in the U.S.A.
