Really Right Stuff B9 Overview

The Bi-Directional Plate from Really Right Stuff is designed to mount to the bottom of a camera or scope. As a result, the plate adds quick release functionality to whatever is being used.

The Arca-type compatible dovetail design is compatible with Really Right Stuff's clamps and ball heads as well as many other Arca-type clamps. The plate's square dovetail design allows your camera to mount in any direction. The CNC machined 6061-T6 aluminum plate has an anodized type II black finish. The plate mounts via a 1/4"-20 mounting screw, and the anti-twist flange prevents the camera or scope from twisting while mounted.

Works perfectly with my Really Right Stuff ball head. They are sturdy, and screw in tight and secure.

Love it, but...

Didn't realize at the time I ordered the RRS mount itself that this needed accessory wasn't included.

Basic and expensive but it does the job.

I finally have a plate that actually holds my camera secure in place. It’s fantastic that my camera no longer slips.

Not thrilled with it on the Leica M10Monochrom

It's ok but interferes with getting the camera's bottom plate on & off and sometimes you have to remove it to align the plate properly.

It is a general-purpose Arca-Swiss plate

It is a general-purpose Arca-Swiss plate A hex screw is used to connect to the camera, and a hex wrench is attached.

I love the fact that this plate can allow mounting in two directions. It is perfectly machined, perfectly sized, and fits snugly into the RSS BH 55 ball-head.

Asked by: Paul
I successfully use this item on my Nikon D850. I also use this item on the collars of my Nikon 80 to 400 mm and my Tamron 150 to 500 mm. lenses. All three pieces are on the heavy side. This plate has served me well. Will it work for your Canon 5D Mark IV? Probably.

Hi. Will the lip/dovetail reach the back of the base on a Pentax K-1? I currently have a similar plate without the lip/dovetail which does not really secure my camera in one spot, so it has a tendency to move around on the plate after a while. I was hoping that the lip/dovetail could reach the end of the base of the camera so that it would kind of lock itself in once tightened down.
Asked by: Courtney
Yes the lip fits perfectly on the Pentax K1 to keep the plate from rotating.

Will this fit snug on a 70-200mm ring and not slip at all?
Asked by: Ryan
The ridge at the rear of the quick release plate of the Really Right Stuff B9 Multiuse Bi-Directional Plate (B&H# REB9PLATE) may make it difficult or impossible to fit on the feet of some feet that are attached to the tripod ring of a 70-200mm lens. To be clear, it is designed to attach to that foot rather than to the ring itself. Either way, please contact us in chat, by phone, or by email to discuss choosing the right quick release plate for your needs as this is not likely to be it.
