This best selling Arborist Block features a wide upper bushing to maximize sling strength and wide side plates to protect the rope from abrasion. One-piece design eliminates lost parts. 3" lower sheave will accept bull ropes up to 3/4" diameter. Stainless steel side plates, aluminum bushing, and zinc-plated steel axle means this pulley stands up to the elements as well as the load.

Ratings & Reviews
Big, heavy, strong, prusik-minding
I use this less because of size and weight but when I need prusik minding or raw strength it gets pulled into service. It has worked perfectly for me since 2016.
