Acratech's Arca-Type Quick Release Clamp with Rubber Knob and 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 a spring-loaded detent pin which helps prevent accidental release of the quick release plate. Weighing just 3 oz, stainless steel construction and the black anodized finish nevertheless give this clamp a solid feel. It has a 3/8"-16 mounting thread and comes with a 1/4"-20 adapter, so it will fit virtually any tripod head.
