    Cut the straps, use mesh screen on outside of tent, screen on inside

Its decent quality, just wish the mesh pad was bigger that way i can wrap it around the vent, this one took me a few minutes to get it perfectly fitted.

    How it attaches to your system!
  

*by B***  on Reviewed in the United States 🇺🇸 on July 18, 2019*

Does what it is supposed to. But should only be placed on the outside of the intake system. If needed for the inside (the last part of your intake) you will need to tape it to your system.
