Master Lock Adjustable Height 2"x2" draw bar with 1 7/8 and 2" ball Convert-A-Balls. This hitch allows you to easily adjust the height to accommodate different trailer sizes while the trailer is attached, ensuring a secure and level connection every time. This spent a few years on my father's truck, so it has rust & wear, but is still able to get full range of height adjustment.
Adjustable Height using a 7/8" wrench or socket to go from 7 3/4" drop or 6 1/4" rise via a worm-gear.
