Q: Are all the stainless steel housings UL Recognized?

A: No, not all stainless steel housings are UL Recognized. The JB7 housing is not UL Recognized, while the M5 and M6 stainless steel housings are UL Recognized as Type 4X. Keep in mind that the final UL certification of your GracePort assembly will depend on the specific components selected and installed within the housing.
