You might be better off not sealing the polyphasers to the box. Just
make sure all the holes are on the bottom, and you'll have no problems.

carry cold air/warm air to that box and make it sweat. I actually
drilled a hole in the bottom of my box at the tower and installed a sink
aerator screen to keep out bugs.
