Vanguard's top-of-the-line ABH-340K semi-elliptical ball head automatically adjusts and increase tension to handle off-center load, with exceptional strength and stability. Patented features include Combination-Friction Forces Control (CFFC) which enables extreme tension and friction control via an ergonomic grooved dial located on the main adjustment knob. Both are independently adjustable but positioned side-by-side on the same axis for convenient fine-tuning. This combination of precise tension and friction forces control increases the strength to provide outstanding security.
ABH-340K has exceptional stability with its Stability X3 system's additional component between the semi-elliptical ball head and housing, providing a loading weight capacity of three times that of other ball head. Other features include an industry-leading housing with oxidation anodizing treatment that provides a smooth, scratch-free surface. It prevents scratching and damaging with incredible resistance. Its quick-release plate has cavity-mounted anti-slip rubber pads for greater camera-to-surface security. A scaled base enables smooth 360-degree panoramic movement. It is compatible with numerous Arca quick release plates so its platform requires no adaptor. K-type knob lock enables fine-tuning.
