Here the top before the stainless steel glide plates are in place. These are the screws that tie it to the ground plate.
Mechanism in "lock" position
Mechanism in open position. When backing into the trailer, the kingpin will close the lock.
Next repositioning the servo support
By moving it to the back the servo horn clears the plate.
The support holds the servo level.
