The Viper cable trolley features dual ball bearings (two sealed bearings in each wheel), giving it an unequaled speed and smoothness. The 10,000lb breaking strength, 1/2" cable capacity, and 120mph speed rating gives you a pulley that will knock your socks off (or your hat). Includes clip-in point for connecting accessories. Requires some assembly.
