ABSTRACT A free standing office or room partition of adjustable height. There is a lower rectangular frame having tubular upright members and an upper rectangular frame having upright members connected to each other by a crossarm and which telescope into the top ends of the upright members of the lower frame. To increase the height of the partition, the upper frame is moved into an upwardly extended position with respect to the lower frame and secured in place. Panels are then fastened onto the upper frame. In a particular embodiment, a screw jack for moving the upper frame with respect to the lower frame is provided. A rotatable threaded rod is threaded through a matingly threaded part of the lower frame. The rod is rotatably connected to the upper frame, but vertically fixed with respect thereto so that rotation of the rod causes the upper frame to move vertically with respect to the lower frame. An aperture is provided at the axial top end of the rod so that an electrically powered drill fitted with a suitable screw bit may be used to operate the jack.
