Skookum Rigging Products
Skookum has stood for rugged strength and gold-standard American forging since 1890. A legacy brand under The Ulven Companies, Skookum is joined by Ropemaster and Ulven Forging, all sharing a commitment to precision engineering and exceptional quality. Skookum products are proudly manufactured in Oregon, USA, and serve some of the most demanding industries—construction, oil & gas, marine, logging, and heavy industrial rigging.
Gold Standard Forgings, Made in the USA
Skookum’s closed-die forging process results in superior grain orientation, exceptional strength, and high dimensional accuracy. Every forged component is backed by destructive testing, CNC-machined dies, and a rigorous quality control process. Whether it’s a lifting shackle or a high-capacity rigging block, the Skookum name means dependability in the harshest conditions.
Industry-Leading Shackles
Skookum shackles are known for their unmatched strength ratings—setting a new bar in the industry. For example, the 263 Screw Pin Shackle in 3/4" size boasts a 9-ton WLL. That's nearly double the capacity of a standard carbon shackle (4-3/4 ton) and significantly higher than even alloy shackles like the Crosby G-209A (7 ton).
- 263 Series – Screw pin anchor shackles with extremely high WLLs
- 320 Series – Bolt-type (safety) shackles designed for permanent or long-term rigging
- 59A and 159A Sheet Pile Shackles – Engineered for piling work; the 159A includes a ground-release feature for remote disengagement
Premium Rigging Blocks for Critical Applications
Skookum blocks are trusted in marine, forestry, construction, and oilfield environments where failure is not an option. They offer a wide range of block styles tailored to specific applications.
- R-Series Rig-Up Blocks (R-4, R-6, R-8) – Compact, full-sided blocks with wide throats for use with a variety of line types and terminations
- 508 and TM-10 Blocks – Larger, wide-throat blocks ideal for oilfield and heavy industrial use, based on the R-Series concept but with increased capacity and size
- 513 and 515 Blocks – Heavy-duty half-sided blocks commonly used as haulback blocks in logging and rigging systems
- Available with bronze bushings, roller bearings, or tapered roller bearings for optimal performance in any environment
