Really Right Stuff B2-PRO II WITH M6 SCREW overview

  • 1Description

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 center socket, which accepts a M6 mounting screw to attach to a head. The CNC machined 6061-T6 aluminum clamp has a black anodized 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 leveled.

    Really Right Stuff B2-PRO II WITH M6 SCREW reviews

    B2-Pro-II Screw Knob Clamp with M6 Screw is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from Excellent machining and operation, finish is adequate Mounted on a p0 head. A bit big for the p0 head, but I wanted a bubble level which the smaller clamp lacks. Ground the screw down about 3mm as it just touched the ball with the head tilted at 90 degrees to the base. Very smooth operation. The clamp knob easily clears the pan knob on the p0. In fact the knob could probably be a bit shorter, even with a MF camera attached. The big knob will work great with gloves. After a dozen or so insertions, adjustments and removals, the finish in the clamp area is visibly worn as seems to be the norm with RRS clamps. Cosmetic issue. Maybe work in a tiny drop of penetrating oil in salty environments. Clamp vs lever versions: I originally mounted the lever version of this clamp as it is more compact and I have found it to works well in other applications. However, I am using some non-rrs rails and they take a fair amount of force to insert and remove making lever use awkward. The screw version, in comparison, is a joy to use for this application.

    Rated 4 out of 5 by from Very precise gear It is a well-constructed product with a very precise operation and a very nice design. The only problem I see is the surface coating that disappears after a few hours of use, in the region of movement of the plate.
