Really Right Stuff B2 AS II, 1/4-20 SCREW overview

  • 1Description

This B2-AS-II Lever-Release Clamp with 1/4"-20 Screw from Really Right Stuff is compatible with most Arca-type camera plates, lens plates, and multi-purpose rails. The jaws of the clamp open wide for plates to be top-loaded quickly and easily with no mishandling of the camera during mounting.

The locking lever-release is opened or closed by only using finger force, and once the clamp is locked down onto the plate, it has a holding power of up to 50 lb. At the top of the clamp, it features a non-threaded, counter-sunk center socket, which mounts through the top via a 1/4"-20 mounting screw. The clamp is compatible with Really Right Stuff, some Arca-Swiss, and Manfrotto ball heads.

The CNC machined 6061-T6 aluminum clamp has a type II black anodized finish. Index marks are laser-engraved on both sides of the clamp so a position can be repeated. Additionally, the stainless steel locking-lever has a low profile, and the lever hugs the side of the clamp very closely, so it is very unlikely to snag onto clothing or something else in the field. The clamp has a built-in bullseye spirit level, which keeps your camera leveled in a horizontal plane.

    Really Right Stuff B2 AS II, 1/4-20 SCREW reviews

    B2-AS-II Lever-Release Clamp with 1/4"-20 Screw (60mm) is rated 5.0 out of 5 by 9.
    Rated 5 out of 5 by from Simply The Best This is the best quick release clamp available at any price, period. It works flawlessly and conveniently. It holds a camera or lens with total security. It can be closed, locked or opened with a single finger allowing the camera or lens to be held securely with the other hand. It is also beautifully made and finished. There are less expensive clamps that do work, but nothing comes close to this for convenience, security and aesthetic quality. I have 2 of these, one for my RRS ballhead/tripod setup and one for my monopod.

    Rated 5 out of 5 by from best upgrade I had been quite unhappy with my old quick release system. I t was difficult to attach the plate and I never felt it was firm. This new RRS clamp is wonderful. It Is extremely easy to insert my new RRS L plate or my Kirk lens plate. When inserted it is very easy to clamp using the lever and holds it very tight, no slop at all. I wish I had changed to this years ago. Best thing I have done for my photography in years. Highly recommended. Ordering from B and H was also very easy and product arrived in just 2 days.

    Rated 5 out of 5 by from Really Right Stuff clamp and L-plate As a precision machinist for 50 years I am very impressed with the RRS B2-AS-II Lever-Release Clamp and the matching L-Plate for the Nikon D850. My older Gitzo tripod and ball head had trouble holding in my heavy ART Sigma portrait lenses and Nikon D850. With the RRS set up my vertical position is rock solid. (A Gitzo plate can be used with a 1/4-20 nut and washer but I made a solid 7075 Aluminum insert in my mounting plate and everything is very solid and a pleasure to use. Worth the price!

    Rated 5 out of 5 by from Superb Lever Release I used this lever release often on a recent vacation and found it to be exactly what I expected - top quality, fast connection and secure. I was a bit concerned that the lever might unlatch during use but found it to be completely secure. It would be very difficult to undo accidentally. Every surface is rounded and polished without a single rough edge. Much attention was paid to details.

    Rated 5 out of 5 by from Beautiful, like all RRS products. It's a bit heavier than I had hoped given my particular use, for panos, while traveling light (With a Nodal Ninja). At least given it's slight heft it's beautifully, precisely crafted, extremely solid. If you need a quick release clamp without a knob that sticks up above the rest of the clamp, this does the trick very well.

    Rated 5 out of 5 by from Greatest! REALLY RIGHT STUFF B2-AS-II Lever Release Clamp The RRS B2-AS-II Lever Release Clamp is very a very well made item. The lever release clamp is fast and simple to operate. I also own the screw knob type clamp which I like very much, however, if you need to save time, the lever type is the way to go.

    Rated 5 out of 5 by from First class photographic equipment.. I replaced the original clamp that came with a new tripod head with the the RRS clamp. The RRS is far superior in every way.
