Shackles are manufactured in a wide variety of types, styles, sizes, and fabrications, and with so many different options available, choosing the right shackle for the job can be confusing.
Bow shackles and anchor shackles are terms that are often used interchangeably, as both names refer to a shackle with a larger, rounded “O” shape look. However, a bow shackle typically has a larger, more defined bow area than an anchor shackle. The rounded design of anchor shackles and bow shackles allow them to take loads from many directions without developing significant side load. The larger loop shape of an anchor shackle or bow shackle does reduce its overall strength, but it is also able to handle a larger strap.Anchor shackle include Screw Pin Anchor Shackle G209,Bolt Type Anchor Shackle G2130, European Type Large Bow Shackle, Commercial Shackle and so on.
Chain shackles are also known as D-shackles. Both refer to the “D” shape design. A d-shackle is narrower than a bow or anchor shackle and generally have a threaded pin or pin close. The smaller loop is designed to take high loads primarily in line. Side and racking loads may twist or bend a D or chain shackle.Chain shackle includes Screw Pin Chain Shackle G210,Bolt Type Chain Shackle G2150, European Type Large Dee Shackle and so on.
Both types of shackles are generally always available in galvanized metal and stainless steel, and all come with different pin options as well.
