Really Right Stuff B2-FABN overview

  • 1Description

The B2-FABN Screw-Knob Clamp from Really Right Stuff is a small, lightweight quick release with a knurled knob, which offers a better grip and more clamping pressure onto a plate. The clamp is compatible with many Arca-type camera plates, multi-purpose bars, camera bars, and L-brackets. There are three strap bosses located on the clamp. The first one is located on the opposite side of the screw-knob, and the other two strap bosses are perpendicular to the jaws of the clamp. Therefore, straps can be looped through, and the clamp becomes a convenient way of carrying your camera around your shoulder or your neck.

A convenient 1/4"-20 socket is located on the bottom of the clamp and gives the option of screwing in a swivel mount and adapting a sling strap. The 1/4"-20 socket also gives the option of adding quick release functionality to many ball heads and monopods that do not have a quick release system.

The clamp has a laser-engraved scale with 1mm increments, so a camera can be positioned precisely or to repeat a position. The clamp is made from CNC machined 6061-T6 aluminum and it has a black anodized type II finish.

    Really Right Stuff B2-FABN reviews

    B2-FABN Screw-Knob Clamp with Strap Bosses (38mm) is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Great For Attaching Accessories This quick release is great for attaching accessories to a camera plate. I use RRS L-plates on all my DSLRs, and I have several accessories that are designed to be attached to the camera via the 1/4"-20 threaded connection. By adding this quick release to the accessory, I can attach it solidly to the camera without fiddling with threaded connections.

    Rated 5 out of 5 by from Easy to use and securely holds gear I am using the clamp on a black rapid strap. The clamp securely and easily attaches to arca swiss mount of my lens foot making quick release fast and unfettered. The knob size is just right and easy to both lock down and release.

    Rated 5 out of 5 by from Top Notch! This is just what I needed! Build quality is second to none. The screw knob holds the clamp in place with no movement. I have no complaints about my purchase of this item.

    Rated 5 out of 5 by from Love this and other RRS Gear Well made Sleek/small design Tried many options this was the best solution
    Date published: 2017-03-16
    Rated 5 out of 5 by from This works and is a good alternative. BlackRapid straps are very popular the biggest issue with them is you have to use their base plates or remove the screw in stud every time you want to use your tripod. Manufactures are coming out with ways to get around this and RRS is no exception. I was contemplating getting the BlackRapid base plate to use with my BH-55 ball head when I noticed this clamp. I liked the Idea that I would not have to remove my base plate on my cameras, or buy specialty base plates, and can use my BlackRapid with more than one camera with very little effort. Prior to getting this clamp I was worried that it might unscrew, and drop my camera. So I bought a tether that attaches to the camera and the strap as extra protection, and piece of mind. After using the clamp for awhile now, I have had no issues with it coming loose. It has a feel of very high quality, and is well thought you with center marks machined into it for placement. Removal and placement is quick and easy, with not having to mess with a lug in the camera or the base plate worrying that it or the camera threads will wear over time allowing the it to come loose. The set screw has a fairly large end for ease in tightening, and machined to go tight when inserted. With screw end turned to the camera lens you can not rub it with your leg unscrewing it.
