• Differences Between Butterfly Vents Part # 371800 and Part # PLR24-002
  The only differences between the vents is that part # PLR24-004 comes with a rubber gasket and part # 371800 does not. The mounting holes are also positioned a little differently. They are both 7-1/4" in diameter and made of a polished aluminum. If you are concerned with rust then I highly recommend using the Butterfly Vent part # PLR24-002 which is made of stainless steel.

A vent such as # WHMAV2-WAVT2 might be a better option. I have linked a video review of this vent and the butterfly vent as well. I...

If you left the vent in either the open or closed position it would move. The amount of friction in the vent assembly would prevent it from moving just from the vibrations of the trailer rolling down the road. With that being said, it is not difficult by any means to...
