Shackles

with 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.

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.
