Screw-Pin Shackles—For Lifting

Screw the pin into position by hand for quick installation and removal. They're for use in low-vibration applications where the shackle remains stationary. Also known as anchor and bow shackles, the wide body provides room to attach multiple connectors.

Black-oxide steel shackles have a dark surface color.

Galvanized steel shackles have a thick coating for corrosion resistance.

316 stainless steel shackles have excellent resistance to salt water and chemicals.

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 Chain Shackles—For Lifting

Screw the pin into position by hand for quick installation and removal. They're for use in low-vibration applications where the shackle remains stationary. A narrow inner opening restricts the movement of wire rope and chain. They're also known as D-shackles.

Galvanized steel shackles have a thick coating for corrosion resistance.

316 stainless steel shackles have excellent resistance to salt water and chemicals.

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.

Heavy Duty Shackles—For Lifting

The strongest shackles we offer, these connectors have a pin with flush ends that prevents snagging and accidental disengagement. They can be assembled and disassembled with a hammer.

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.
