CME dimension request?

But my rear valance measures 1.75 on the cutout, and 4.0 on the overall height.
Hope this helps you out.
I will try and get pictures and do a formal introduction this weekend.
Why do you need that particular space (as oppose to the actual opening)?
am mocking up a valance and wanted a rough measurement on how low should i extend. i think am going with a tip on each side. am aware of them being sold but this is something am doing for fun
