Acratech's Arca-Type Leveling Quick Release Clamp with Detent Pin will work with any quick-release plates that are Arca-Swiss compatible. This clamp features a double speed tightening knob that opens and closes twice as fast as standard clamps. The knob is also permanently secured and cannot fall off or be lost. It is rubber-coated and allows for more certain operation in cold conditions. This clamp has highly visible bubble level for leveling your camera. There is also an embedded, spring-loaded detent pin which helps prevent accidental release of the quick release plate. Weighing less than 3 oz, stainless steel construction and the black anodized finish nevertheless give this clamp a solid feel. With 3/8"-16 and 1/4"-20 mounting thread adapters, it will fit virtually any tripod head.
