Note: inside dimensions of the curb is a tight 11 7/8" x 11 7/8" x 3" high.

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 excepts typical residential dryer exhaust conduit. Per building codes, there is no screen in this vent as it is exclusively designed for clothes dryers. Unlike other roof vents this vent features a unique light-weight damper that is curved which increases the efficiency dramatically. The final opening is 50% larger than the round pipe portion. By far, this is 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 locatoin favors the rear. See drawing showing 2.5" from rear edge. This vent is proudly made in the USA.
Professional installation is recommended.
