Just a short note to tell you how impressed we are with this vent. During hurricane Ike (we are in the Turks and Caicos Islands), the wind was gusting to 135 mph with driving rain. I went out the next day to mop up the garage where the vent (an AV-10-C2) was installed. To my surprise, not one drop of water came through the vent!! A great product.
PS. I did replace the metal sheet metal screws with stainless steel screws as we are on the ocean and only stainless last over 6 months – an option that you could consider.
(two pictures show damage from Hurricanes Ike and Hanna to the causeway and our porch)
