By machining the side plates, the thickness of the metal can be optimized to maximize the strength-to-weight ratio, a process that cannot be done with the traditional bent metal side plates. The unique axle assembly delivers a smooth side plate and impressive strength. The aluminum sheave is mounted on sealed ball bearings for high efficiency. Ideal for small block-and-tackle kits. Compatible with rope diameter up to 11 mm (7/16 in).
Do not load a single side only of a double sheave pulley.
