Really Right Stuff RRS-9000047 Z 9 Base Plate
The engineeringly gorgeous Really Right Stuff Z 9 base plate has arrived, and it’s perfect! It’s lighter than what I was using, and securely fits with that “lock-in” post along with the 1/4 20 thread. It comes with an L Wrench that as you see has a compartment in the plate held in place by magnets. It comes in two versions, this is just the base plate version.
