This medium sized Galvalume® roof cap has a plate (flange) size of 12” wide x 12” and the structure is 6” wide x 8” and about 9” high. It has a 4.12 inch diameter collar that accepts typical residential dryer exhaust conduit. This vent meets all building code requirements for dryer venting. It features a unique, lightweight damper that is curved to deter nesting birds and rodents, preventing entry into the dryer exhaust system. The final opening is 50% larger than the round pipe portion, making it by far the most efficient roof vent on the market.
Galvalume: A patented alloy of barrier-resistant aluminum and corrosion-fighting zinc gives Galvalume its superior corrosion resistance. Most Galvalume substrates feature an alloy that is 55% aluminum, 43.5% zinc and 1.5% silicon. Tests have proven this alloy superior to the zinc-only coating used in regular Galvanized sheeting.
Additionally, it is Acrylic Coated, coating designation AZ-55. The collar penetrates the plate about 1.25 inches and is sealed to the plate with a silicone bead. Collar location favors the rear. See drawing showing 2.5" from rear edge. This vent is proudly made in the USA.
Professional installation is recommended.
