OD collar to the handle of the tandem pin handle, the collar is attached to a 24? steel chain, then the driver will attach a steel clevis hook that is attach to a 6 inch steel chain, that is attached to a 24 inch steel pipe with a 45 degree curve in the upper end of it with a 4¼? plastic grip on the bottom of the pipe and two 1¼? grips on the Tee, keeping pressure on the chain, the driver while in a standing position, will then by holding the end of the steel handle place the 5½? on the side of the trailer, about two inches up the side. Then he will pull upward on the handle, which pulls on the hook, which pulls on the collar that is attached to the handle of the tandem pin. This will release the pin, allowing the driver to adjust the tandems.
