The Manfrotto 494 Mini Ball Head has a load capacity of 8.8 lb and can be attached to tripods or other support systems that feature a 3/8"-16 mount. By loosening the 494 Mini Ball Head's locking knob, its ball-and-socket joint can be quickly swiveled, angled, fully tilted, or returned to its upright position. An additional knob opposite the locking knob can be rotated to apply tension control to the ball-and-socket joint's movements.
