The Quarrix Smart Plug™ Roof Patch is the smartest solution for covering holes in the roof -- FAST! It easily installs in seconds -- Place It -- Nail It -- Done! It is an easy plug solution that makes converting from static vents to ridge ventilation products faster and stronger than other methods. Cutting and bracing plywood to fit the hole is time-consuming and covering it with sheet metal does not meet most local building codes. Can be installed with a nail gun.
