Arborist Pulley

Designed for use in false crotch systems to help save wear and tear on Bull ropes. Upper bushing maximizes sling strength and wide sideplates protect the rope from contact with rough bark. The upper bushing will accomodate slings up to 3/4" in diameter; the 3" lower sheave will accept bull ropes up to 5/8" diameter. Convenient knurled knobs allow for easy rigging of the upper bushing. Fabricated from stainless steel and aluminum for lasting durability in outdoor conditions.
