Stainless steel and ENT – with stainless 401 escutcheon with a tiny little screw going from cup to skirt in a local aircraft facility seems to work really well. The screw is a great idea.

These are places where they wash down the ceiling on a regular basis. Is it mostly Stainless Steel or ENT being used out there, with semi-recessed or 1 piece escutcheons?
