User questions & answers

Question:	Can this be installed on a vertical surface such as a wall
Answer:	Not likely, the bearing only works if it's perfectly level. There's some articulation in the mount to keep it level, but definitely not 90 deg.
Question:	dose this have to be on a flat surface? can I install it on a pitched roof
Answer:	The vent comes with instructions showing how to set the correct pitch for your roof style. This is not only for a flat roof installation.
Question:	I live in a cool coastal climate and need to reduce moisture/molding. Will this help
Answer:	Yes
Question:	Can rodents (specifically roof rats) gain entry through the vent
Answer:	That would be difficult as these things r constantly spinning. What I did was put a fine wire mesh in the attic under the hole that was cut to prevent wasps from entering. Stapled it and have had no issues.
