This is the most popular "general rigging shackle" we sell to our logging customers here in the Pacific Northwest, and it is used in a wide variety of rigging applications. It is made from hand forged alloy steel, right here in Oregon. The strength-to-weight ratio on these shackles is very impressive, and they hold up well in logging applications.
