The leveling foot described quickly self-stores, ships attached to frame, and adjusts quickly into position. Previous self-storing leveling feet of this type have had a continuous threaded screw. This requires the leveling foot assembly to be threaded the entire length of the screw to arrive at the storing position. By removing the threads from the portion 1 of the screw that is not needed for leveling adjustment (the area of threads that is engaged when the load transfers from the leveling foot to the caster), the leveling foot can easily be pushed up into the frame after threading past the adjustment threaded area 2. The foot assembly can now be secured by engaging the selfstoring threaded area 3.
