Also commonly called screw pin chain shackles, aka D-shackle due to its"D"shape, they are intended for use in straight line pulls or lifts only. These galvanized chain shackles are excellent for use with single leg web lifting slings such as nylon slings and polyester slings. When paired with chain, they provide a connecting link to connect to other hardware. It's important to note that they should be used only with single leg slings, as slings with multiple legs could cause side loading conditions.
