Anchor Shackles for Lifting

Your go-to choice for connecting hooks, slings, and other rigging and lifting equipment. The rounded body on these shackles supports vertical or side loads without fatiguing or warping the shape. They meet ASME specifications for rigging and lifting, so they can hoist everything from steel beams to bulldozers. Look for the manufacturer's stamp to confirm the size and weight capacity. Also known as bow shackles.

Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the shackle can lift is significantly reduced.

Screw Pin—The most common shackle pin type. Although the pin easily connects and disconnects, it can come unscrewed or wear down over time, so it's best for temporary use.

Safety Cotter Pin—Both a threaded nut and cotter pin hold these shackles in place. Also known as bolt-type shackles, the pin won’t slide out with movement. This means you can use these shackles with vibrating equipment and for long-term rigging setups.

Black-Oxide Steel—The dark finish on these shackles resists occasional moisture.

Galvanized Steel—A thick coating protects these shackles in wet and outdoor environments better than black-oxide steel. However, they corrode when exposed to salt water and chemicals.

Super-Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant shackles stand up to moisture, salt water, and chemicals.

D-Type Shackles for Lifting

The best choice for lifting with chain. The bow and pin are equally wide to keep chain links from sliding or moving and support heavier vertical loads than anchor shackles. However, they're rated for vertical lifting only, as side loading might deform the bow. All meet ASME specifications for use with rigging and lifting equipment. Look for the manufacturer's stamp to confirm the size and weight capacity. Also known as chain shackles.

Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the shackle can lift is significantly reduced.

Screw Pin—The most common shackle pin type. Although the pin easily connects and disconnects, it can come unscrewed or wear down over time, so it's best for temporary use.

Galvanized Steel—A thick coating protects these shackles in wet and outdoor environments better than black-oxide steel. However, they corrode when exposed to salt water and chemicals.
