The B2-Pro-II Screw Knob Clamp from Really Right Stuff is compatible with most Arca-type camera plates, camera bars, and multi-purpose rails. The knurled knob of the clamp offers a better grip, so you can apply more clamping pressure onto a plate. The jaws open wide for plates to be top-loaded quickly and easily.
The clamp has a non-threaded, counter-sunk centre socket, which accepts a 1/4"-20 mounting screw to attach to a head. The CNC machined 6061-T6 aluminium clamp has a black anodised type II finish. Index marks are laser-engraved on both sides of the clamp so a position can be repeated reliably. The clamp has a built-in bull's-eye spirit level, which keeps your camera levelled.
