I like the easy install. The unit works great.However though it was shipped in a wooden crate, it was slightly damaged. Sue to take I chose to not return it.Has a 3 prong plug. But no ground prong. I added a ground wire that tied to the chassis.Good product overall.
This exhaust fan is much larger than I thought but a great fit for my food trailer. It has a three-prong plug which is easy to modify. Definitely suggest adding rust-proof spray and waterproof sealant.
