Wichard forges non-magnetic, low carbon steel (316L and 305 Cu) and transforms it into reliable shackles that withstand the test of the marine environment. Wichard's innovative captive pin shackles were designed for better handling, and have a captive pin that cannot be lost even when it is unscrewed.
Wichard's captive pin shackles also have a patented self-locking feature. This Long D Shackle with a captive pin has a coined headpin with a diameter of 1/4 (6mm). The coined shackle pin is drilled to accept seizing wire.
