The DryerJack Model DJK486B roof vent termination is specifically designed for dryer venting. Its precision-tuned design creates no resistance, giving a level of performance previously unavailable in the industry. Features include an industry-first curved damper that deters nesting birds and critters and a wider opening to provide easy access for cleaning and maintenance. The sturdy 26 gauge Galvalume® steel housing with corrosion-resistant powder coated finish is built to last. This extra clearance vent is best suited for medium snowfall regions, sloped roofs with flat profile cement tiles other composite shingles. Does not provide adequate clearance in height for "S" or Barrel Tile roofs.

This medium sized Galvalume® roof cap has a plate (flange) size of 12” wide x 14” 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 65% larger than the round pipe portion. By far, this is the most efficient roof vent on the market.
For flat roof installs, we recommend a installing our DJK486U (curb style) over a raised curb. Search the part number above.
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 is only 5 inches between the opening and the bottom plate. Bird nest building within would be doubtful due to the slope and shape of the damper. This vent is proudly made in the USA.
