[RE-wrenches] Thermal issues with PVC (was RE: raintite box mounting angle)

[Drake Chamberlin]

You can get metal NEMA 4 and NEMA 12, gasket sealed boxes made by 
Hoffman.  There should be no deformation issues.  The only possible 
issue could be the temperature of the gasket, but it would be held in 
place by the clamped cover.  Have the gaskets had an issue with the 
deformed PVC boxes?
