Use this to set the height of your couplers.
The couplers should be set 1/32" from the top of the track to the bottom of the weight on the couplers.
With hub facing down between the track rails you can easy slide it back and forth.
When check the knuckle coupler make shore it is in the closed position and the weight is fully extended down.
It should barley touch the top of the gauge.
Do the same with the link couplers.
Make adjustments to the couplers if needed.
