A leg for use in supporting geometric equipment includes a first leg section and a second leg section for telescoping receiving the first leg section. A locking device includes an actuator and an engagement portion. The locking device is operable in a lock position in which the engagement portion bears against the second leg section on the interior thereof with a force selected to lock the first and second leg sections with respect to each other, and an unlock position in which the engagement portion is spaced from the second leg section such that the leg sections are free to move in telescoping relation with respect to each other.
