Rate & Review

The Manfrotto Hydrostatic Arm features a new locking mechanism. A ball pivot encapsulated in a hydraulic oil-filled chamber enables the arm to be locked in position with only a gentle turn of the knob. This is accomplished by the fact that the oil surrounds the ball joint and applies pressure evenly, as opposed to a traditional lock that simply jams a screw or cup against the ball.

The 8191 Medium Hydrostatic Arm spans 7.1" (18 cm) and is a perfect bridge between a video camera and a small monitor under 4.9 lbs (2.2 kg) in weight. It also features both 3/8" and 1/4"-20 pins with standard tripod/camera threads.

  • Length: 7.1" (18 cm)
  • Weight Capacity: 4.9 lbs (2.2 kg)
  • Weight: 0.4 lbs (0.2 kg)
  • Warranty: 1-Year Manufacturer's Warranty
