Redsea Universal Arm measurements

[Snoopdog]

Does anyone that owns the Redsea Universal arm have the time to measure the width and depth of the part that sits in the tank? Preferably a picture? I have a set of Reefled 90 that need to go in a tank that has Radion right now and I want to see if the brackets will mount cleanly.

Is your tank rimless or rimmed?

Planet Aquarium, rimless. I know the arm will fit the tank though, I have a custom acrylic lid so I am trying to make sure the cutouts will at least be smaller for the Redsea arms.
