The Leofoto GC-282AL is an aluminium boom arm with a geared extender. It attaches to the neck of a tripod replacing the existing head, which is then attached to the end of the arm. The arm has a grip knob at the rear end which is also the combined lock for the pan & tilt action. There's a locking wheel at the end to stop it slipping when in the upright position, and a friction knob to adjust the tension on the geared action.
