Forestry Shackles – Built for Logging and Timber Operations

Forestry shackles are specifically designed for logging and timber harvesting, making them a staple in large-scale forestry operations, particularly in the Pacific Northwest, where professional loggers rely on rugged, high-strength hardware. Unlike standard rigging shackles used in construction and industrial lifting, forestry shackles are built to endure the extreme forces and harsh conditions of logging work but are not designed or rated for overhead lifting applications. Ulven, the parent company of Skookum and Ropemaster, is well known in the industry for manufacturing durable shackles and fittings trusted by professional loggers. Popular models include:

• Ulven #101 – A standard screw pin forestry shackle, commonly used for quick and secure connections.
• Ulven #102 – Shares the same footprint as the #101 but features a bolt and nut for added security in long-term applications.
• Ulven #110 – A unique flush pin design that minimizes snagging, making it ideal for logging operations where obstruction-free performance is needed.

Ulven shackles are ideal for heavy-duty forestry work, but they are not intended for construction operations or any application involving overhead lifting. For general rigging and lifting, standard shackles like the Crosby G-209 or Van Beest Green Pin G-4161 should be used instead.
