Anchor Shackles for Lifting

Screw Pin

Safety Cotter Pin

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.

High-Strength Galvanized Alloy Steel—Stronger than galvanized steel with corrosion resistance in wet and outdoor environments.

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

D-Type Shackles for Lifting

Screw Pin

Safety Cotter Pin

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.

Anchor Shackles

Screw Pin

Flush Screw Pin

Safety Cotter Pin

The most common choice for connecting slings, hooks, and more. The bow on these shackles is wider than the pin to support loads from multiple directions and accommodate multiple connectors. They’re often used to tie down or secure loads for transport or storage. Also known as bow shackles.

Warning: Not for overhead lifting.

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.

Flush Screw Pin—The ends of the pin sit flush with the shackle, so they won’t snag or catch on anything that might loosen the shackle.

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

Flat Shackles for Lifting

Screw Pin

Safety Cotter Pin

Lift with web slings. The wide, flat bow on these shackles prevents your sling from folding or bunching to keep loads distributed equally. All meet ASME specifications for rigging and lifting equipment. Look for the manufacturer's stamp to confirm the size and weight capacity. Also known as webbing 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.

High-Strength Painted Alloy Steel—The paint provides some corrosion resistance, but can chip or wear away over time.

D-Type Shackles

Screw Pin

Flush Screw Pin

Safety Cotter Pin

Pair these shackles with chain to pull and tow loads. The narrow bow prevents chain links from sliding or moving, but they're rated for inline tension only—they can’t handle pulling or tension to the side. Also known as chain shackles.

Warning: Not for overhead lifting.

Hitch Inserts

Insert Shown with Hitch-Ball Components

Use these inserts in hitch-ball connections for towing. They fit into a receiver that's attached to a vehicle. Maximum trailer weight is the total weight being towed. Vertical capacity (also known as tongue weight) represents the weight of the load on the hitch ball.

Shackles

Shackles pivot around a pin, so you can choose the right towing angle. Tighten the pin to secure the shackle in place.

Flexible Shackles for Lifting

A flexible and lightweight option for lifting. Made of polyethylene rope with a nylon cover, these shackles wrap around a variety of lifting points without marring surfaces. All meet ASME specifications for rigging and lifting equipment. To close them, pull the bar through the loop and slide the rubber lock over each end of the bar. Keep these shackles away from sharp edges, which could cause them to break and fail.

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.
