Retrofits

The Vent That Protects

Our retrofit kits and matrixes are available simply for existing installations where removal of current hardware is unrealistic. The honeycomb matrix along with the screen mesh (sold together) can be used in a variety of retro-fit applications. Inside the attic, behind existing gable and eave vents, the matrix can be cut to size and fastened to the existing 1/4” screen. Retrofits are as easy as 1, 2, 3. Please feel free to contact us if you have any questions!
