Designed for supporting teleprompters and studio cameras weighing up to 60 lb, the PSGAIRLIFT60B Pedestal Deluxe Pneumatic Center-Post Tripod from Davis & Sanford features a broad base to prevent tipping and 4" wheels with ball bearings to smoothly and quietly move the tripod around the studio. Step-on brakes lock the wheels in place to prevent swivel and rolling action. A pneumatic cylinder in the 4" center column enables smooth and easy height adjustment that, when paired with the dual strut tripod legs, provides a working height range of 31.5 to 47.5". A removable adapter with 3/8"-16 screw allows for quick attachment of a camera or separately available tripod head to the pedestal.
