Acratech Ultimate Ballhead without Quick Release, with Left Rubber Knobs & 3-8"-16 Screw - Supports 25 lb (11.3 kg)

Quick Overview Absolutely no migration after tightening the clamp Silky-smooth black andonized finish for precise positioning Open design facilitates quick maintenance Calibrated panning bed "Dry" ball does not attract dirt or dust Fully captive controls will not come off from prolonged vibrations Product Description The Acratech Ultimate Ballhead is the result of an innovative efficient design, created for combining low mass with incredible stopping power. Available with or without an installed Arca-type quick-release clamp, it is an ideal head for those that do not require the progressive tension control of the heavier (and more expensive) Arca-Swiss B1. The innovative design of the Acratech gives the photographer full access to 25% of a sphere at any time, and it is entirely capable of providing support in any direction so long as the tripod legs are not overwhelmed. Model #1116 features rubber knobs on the left side of the head, which are more comfortable to operate
