Attaching safety chains to a hitch receiver when using a drop hitch can be very difficult or simply impossible under certain circumstances. Safety chains connect the trailer to the hitch receiver and provide a back-up in case the coupler detaches from the ball. They are generally set long enough to allow the trailer to turn without binding up however short enough to stop the chains dragging on the road surface. With this 5/8" shackle, you can attach your safety chains to anywhere on the hitch, such as a pinhole or a second attachment. This allows you to get the correct safety chain length without the need for chain extenders. The shackle is coated in black powder coat to match the rest of our high-quality accessories and hitches. These shackles are rated at 6,500 pounds each.
