The Really Right Stuff B90D plate is custom made to fit the Canon 90D camera body, utilizing carefully placed anti-rotation flanges around the plate. Cutouts enable easy usage of the 90D flip-out LCD screen. 
Each individual plate is precisely CNC machined out of 6061-T6 aluminum billet. This enables the B90D to be reliably compatible with any Arca Swiss-style or standard 1.5"-dovetail-style quick-release system. It attaches to the Canon 90D tripod thread mount using a custom captive flathead1/4"-20 screw, included with the plate.

The B90D-L bolt-on vertical L-Component combines with the B90D base plate to create a fully modular L-Plate with two dovetail mounting surfaces. You can purchase the L-Component as a separate add-on or as included in the L-Set.

Arrived today, 12/4/2019. Absolutely perfect, the usual RRS high quality. It fits perfect, all controls available. It does not interfere with the flip out rear screen at all. Very high quality with lots of additional machined in places to attach other accessories. I am really happy with this mounting plate for my new Canon 90D. Very highly recommended.
