Product Description

Only the Skookum R Series offers both wide throat and Utili-Sheave. A wide throat makes it much easier to pull a variety of line, connecting links, or oversized line conditions. Wide manganese steel Utili-Sheaves work harder and last longer. These blocks are the choice of operators for heavy duty work. Built with no superfluous weight but a big reserve of strength and ruggedness. Equipped with long life Timken Bearings. Yokes and yoke pins are forged and heat-treated alloy steel. The block sides are the frame of the block--the unique shape fenders the rim of the sheave providing maximum protection from line jamming while minimizing weight which are both critical to performance.

  • A true rigging block for loggers
  • Wide throat allows eyes and rigging to pass through
  • Heavy-duty design with tapered roller bearings
  • Sheave made of Manganese for durability and long lifespan
  • Commonly referred to as a "Tommy Moore" block

I lost one of the pins for my skookum. Are you able to sell me that?

Most likely, yes.  Just give us a call @ 503-399-7037 and ask for Mario or Gary.  We might even have the pin in stock at our Eugene store (depends on which pin you need).
