All of our link tabs are LASER cut for precise hole sizes and clean edges. These tabs are our Long Round model- 3.645" from the center of the 9/16" hole to the top of the round base. Round edge is based on a 3" axle tube, and can be rotated for upper triangulated bars. 1/4" thick steel provides a solid platform for your link to mount.
We also offer a bunch of other styles of tabs and brackets to suit your needs- browse around, and contact us if you don't see what you need!
