I see this sticks to most surfaces. How do you cut out the hole before or after it's installed?
Asked on 03/06/2012 by Bill BOnce the shrinkwrap is tight, place the vent on the surface and measure what area needs to be cut. Remove the vent, make the cut with your utility knife and stick the vent onto the surface of the shrinkwrap.
