Gasket Only for 2-Way LOW PROFILE ROOF VENT
This is a black 1/8" thick closed-cell foam gasket. Closed-cell foam means the gasket won't absorb water, so it prevents the two-way roof vent from leaking. Installs between the vent & the trailer roof.
The perfectly-shaped gasket allows it to be used as a template to cut the correct shaped hole in the roof of the trailer & includes matching holes to the holes already drilled in the vent lip.
We highly recommend that these gaskets be installed with the aluminum two-way low-profile roof vents.
