Introducing the DryerJack® Model DJK477B, designed to meet the more stringent requirements of venting a clothes dryer through the roof. This low profile, advanced model combines a unique curved damper and larger vent opening to promote superior airflow efficiency.
Proudly manufactured in the USA from heavy gauge Galvalume® steel, the engineering is focused on three critical aspects: Optimizing airflow, preventing birds and rodents from entering the dryer exhaust system and providing easy access for duct cleaning.
This low-profile style vent is best suited for medium snowfall regions, sloped roofs with flat profile cement tiles and other composite shingles. Does not provide adequate clearance in height for "S" or Barrel Tile roofs.
Additionally, Model DJK477 DryerJack and The RoofNeckTM Kit, a transition connection between the internal duct work and external roof vent termination, makes it easier to install and connect the duct work to the roof vent.

Unlike other roof vents, this vent features a unique lightweight, curved damper and larger vent opening. The combination of the curved damper and a larger vent opening allow for maximum airflow efficiency, helping to reduce lint buildup and potential safety hazards. Drying time is reduced, saving energy and equipment wear and tear.
Get protection from pests! The unique low-profile curved shape combined with the position of the damper inside the hood when closed deters birds and rodents from entering.
DryerJack Model DJK477 dryer roof vent is quality constructed of Galvalume® steel and is built to last. The plate (flange) size is 11.75” x 11.50” with a 1.5" nailing flange on all four sides. It has a 4.12 inch diameter collar that accepts typical residential dryer exhaust conduit.
For flat roof installs, we recommend a installing our DJK486U (curb style) over a raised curb. See related items below. The collar penetrates the plate about 1.25 inches and is sealed to the plate with a silicone bead. It will work on sloped roofs from 2/12 up to 12/12.
Note: Not recommended for use with a high-profile roof tiles like "S", Spanish S as there are only 5 inches between the opening and the bottom plate. 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.
Complies with 2017 code M1502.3.1 (Exhaust termination passageway size).
Professional installation is recommended.
DIY'ers, we recommend Polyurethane Roof and Flashing Sealant
Not recommended for bathroom exhaust fans with less than 70 cfm output.
