Eye End

Push the spring-loaded pin or collar to fasten these shackles, then pull it to release them. Traditionally used to secure and adjust lines on boats, they open faster than shackles with a screw or cotter pin.

Warning: Not for overhead lifting.

Pin-Release Shackles—Attach a rope, chain, or other pull to the pin to open the shackle from a distance. The end connection swivels for easy connecting and adjusting.

Collar-Release Shackles—Pull the collar or sides of these shackle to open them. The collar keeps the shackle closed and smooth sides so it won’t snag surfaces or get pulled open accidentally.

High-Strength 17-4 PH Stainless Steel—Made from one of the strongest types of stainless steel, these shackles won’t deform from vibration or stress. They also stand up to wet and outdoor environments.

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

Release-Under-Load Shackles

Pull the lever on these shackles to release loads, even under tension. By attaching a rope or chain to the lever, you can open it from afar. Precision made in the U.S., these shackles operate smoothly even in harsh sea conditions or high temperatures. They're ideal for safely releasing everything from lifeboats to fuel tanks into the water or onto the ground.

Warning: Not for overhead lifting.

15-5 PH Stainless Steel—Made from one of the toughest types of stainless steel, these shackles undergo heat treatment for extra strength and withstand impact and wear. They also resist corrosion from chemicals and salt water.
