As a professional marine chain and chain accessory manufacturer, we produce common shackles, as well as adjustable shackles used to connect chains and other shackles to adjust the total length of the anchor chains. As a marine device, we supply adjustable shackles in two different grades: Gr40 and Gr8.8. They can be galvanized with an 85µm thick layer of zinc on the surface.
