The Sirui A-10R Profi ball head with gear assisted locking device and a flat design for high performance. The A-10R head works precisely and smoothly. With its load capacity of up to 20kg, it has your camera firmly under control. The base can be rotated through 360 degrees. The locking knob for the ball is gear-supported and ensures a particularly firm hold. It can be limited by a scale in the end stop. This allows you to adjust the mobility of the head individually to your camera. This prevents the ball from loosening too much, for example, and thus prevents the camera from tipping over unintentionally. The clamping device for the interchangeable plate is compatible with the Arca Swiss System and allows the use of various plates. This quick release plate from Sirui has a 1/4 inch standard threaded screw and a rubberized surface. Two red sliding stoppers additionally stabilize the camera or lens when tilting the head or for portrait shots. The 1/4 inch screw can be fastened without additional tools thanks to the screw-on bracket.
