Great for the needed air flow in my old enclosed trailer gets really moist and stale air when sealed for long periods of time.

Stopped my tools from rusting. The moisture in my 6x12 cargo trailer was crazy until i installed one of these on each side

I installed two of these in my 5x8 enclosed trailer. Everytime I opened the trailer is was so humid in there. I used a hole saw that was the same size as the round piece that goes inside the trailer. These are good quality. No hardware was included so I sprayed some self tappers with some black spray paint and applied some Silicone along the back top and sides before screwing to the trailer. I highly recommend these and I would.purchase them again.

Like its made in the USA, its a better looking vent and any other. Material feels tough. and a good price. ty

Had a white vent set on my trailer for a few years and it cracked so i figured id replace it while i upgraded trailer lights also from tecniq and covert. Build quality looks good and the design seems to be alot better than the previous one i had installed
