Claim:
A leg for use in supporting geometric equipment comprising a first leg section and a second leg section having an interior surface facing toward a longitudinal axis of the leg, the first leg section being telescopingly received into an interior of the second leg section for selective extension from and retraction into the second leg section to lengthen and shorten the leg, and a locking device including an actuator and an engagement portion positioned to act on the interior surface of the second leg section to lock the first and second leg sections relative to each other to fix the length of the leg, the locking device being operable in a lock position in which the engagement portion of the locking device bears against the second leg section on the interior surface thereof with a force selected to lock the first and second leg sections, and an unlock position in which the leg sections are free to move in telescoping relation to change the length of the leg, the engagement portion being engageable with the interior surface of the second leg section in the lock position at different location substantially continuously along a length of the second leg section for substantially continous adjustment of the length, the locking device being mounted in the first leg section and projecting longitudinally outwardly therefrom into the second leg section, the locking device including at least one ear projecting outwardly therefrom through a hole in the first leg section to connect the locking device to the first leg section.
