Apparatus for adjusting the longitudinal and angular position of a work surface support leg is disclosed. The leg passes through a channel in a cap held via a spring and pin to a base. The leg's angular position is adjusted by rotating the cap, moving a tooth through a series of mating depressions, while the longitudinal position is adjusted by moving the leg with a series of notches that mate with a locking tooth in the cap. A knob interfaces with the cap via a rotary cam having high and low steps and a matching cam rider. The low step allows separation between the cap and base and the high step locks the cap to the base, thereby locking in the adjustment setting for the leg. The invention affords superior convenience when making angular and longitudinal leg adjustments, especially for people with physical handicaps.
