Joining the stud link chain and the anchor, a 3-link or 4-link swivel forerunner is the most common swivel-connector in use today due to its optimal design. The anchor-side of the swivel forerunner is open for fitting a āDā end shackle. The other side is a common link to fit a Kenter joining shackle.
