The ETL Listed Mark is proof of product compliance to North American safety standards,
including UL, ANSI, CSA, ASTM and NFPA standards.
We offer two models for situations in which an ETL listed hood is required by local code:
(exhaust-only) and BSSM48-ETL (with built-in Make-Up Air chamber). 
Both models include installed light fixtures and built-in 3" standoff at the back of the hood.
