ARCA-SWISS monoball®p tripod heads are characterized by sleek design and simple intuitive handling without knobs or handles getting in the way. Equipped with an aspherical ball and three internal locking elements, monoball®p tripod heads provide a firm hold on the ball. The patented design applies a uniform force around the ball, ensuring ultra smooth movements of the camera on any axis. Fast and intuitive, one knurled locking ring on the head loosens and tightens the monoball®.
