Product review (1 stars): Flimsy construction and arrived broken
What a piece of junk!
I have a 2011 Forest River Surveyor with a white Ventline  brand range hood vent.
I broke it by hitting it with with my washing brush!!  Ack!
I wanted to get a black one to replace it so it would match my window frames.  Also, black lasts longer in the UV than white.
I purchased this one and ran out of summer so I had to wait a year to put it in.
I went to install yesterday it and I discovered one of the flap locks were broken off and the vent flap was so warped it wouldn't stay closed!
I stored it in a cool dark garage so I wonder what it would have done on a hot outside trailer wall!
Do yourself a favor, get the original Ventline brand range hood vent instead.
They come in white an black, are cheaper, and they are made in USA.
