[RE-wrenches] Convex modules

[Jay]

I’m wondering if it’s designed to account for gravity sag once the modules are mounted. Lots of modules I’ve seen especially the larger format ones seem to be concave with time. 

If I understand correctly, these are bowed up which would allow them to settle flat?

I will check specs.  I doubt that testing will reveal anything immediate, but I'm a bit concerned about the potential long term effects.
