Claim:
A leg for a workbench, comprising: an aperture positioned near a first end of the leg and extending between a first side of the leg and a second side of the leg and perpendicular to a longitudinal axis of the leg; a first cam surface extending between the first and second sides of the leg; a second, flat cam surface extending between the first and second sides of the leg and adjacent to the first cam surface, the second cam surface lying farther from a longitudinal axis of the aperture than any portion of the first cam surface; a third cam surface extending between the first and second sides of the leg and adjacent to the second cam surface, the third cam surface lying closer to the longitudinal axis of the aperture than any portion of the second cam surface; and a first locking surface extending between the first and second sides of the leg and adjacent to the third cam surface, the first locking surface defining a first plane that is substantially parallel to the longitudinal axes of the leg and the aperture, and lying farther from the longitudinal axis of the aperture than any portion of the third cam surface, the second cam surface defining a second plane lying perpendicular to the first plane.
