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.

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

Anchor Shackles

Screw Pin

Captive-Locking-Screw

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.

Captive-Locking-Screw Pin—The pin on these shackles won’t fall out or get lost. Even when unscrewed, an inner lip on the shackle ear keeps the pin from sliding all the way out. Indentations in the shackle body hold the head of the pin in place once fastened to secure it from vibration and movement.

Long-Reach D-Type Shackles

Screw Pin

Locking-Screw

Captive-Locking-Screw

Gain extra reach with these shackles. With an elongated body, they can connect loads to an anchor point too far for a standard shackle. They're best paired with chain, since their narrow bow prevents chain links from sliding or moving. These shackles are rated for inline tension only—they can’t handle pulling or tension to the side.

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.

Locking-Screw Pin—Indentations in the shackle body hold the head of the pin in place once fastened, so the pin won’t loosen from vibration or movement as easily as other screw pins.

Locking-Screw Pin

Captive-Locking-Screw

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.

90° Twist Shackles

Screw Pin

Connect loads perpendicular to your anchor point without any twisting or knotting. The bow on these shackles is twisted 90° from the orientation of the pin, so they keep chain, ropes, and slings connected to the load and lifting point properly aligned.

Warning: Not for overhead lifting.
