  • 6" Wide x 8" Body
  • Part Number DJK486
  • 26 gauge Galvalume® sheet steel

Additional Description:

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 8” 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. 

The collar penetrates the plate about 1.25 inches and is sealed to the plate with a silicone bead.  It will work on a flat roof as long as there is no chance of standing water greater than 3” and sloped roofs up to 12/12.  Note: Not recommended for use with a very high-profile roof tile like true Spanish Barrel (cap and barrel) as there is only 5 inches between the opening and the bottom plate.  Nest building within would be doubtful due to the slope and shape of the damper.  This vent is proudly made in the USA.

Professional installation is recommended.

Not recommended for flat roofs where the water level could exceed 1” due to the inability of the roofs’ drains to dissipate the water.
Not recommended for for bathroom exhaust fans with less than 70 cfm output.

Dryerjack extra clearance roof vent
Customer service via phone was excellent. It was explained to us there was a backlog in production and to check back. We ordered couple weeks later and got the item in mail in good time. Product installation was straight forward. THIS PRODUCT CUT OUR DRYING TIME IN HALF!!! We searched for a product locally in Canada and nothing came close to the superior quality and design of your product. We got the extra clearance design as we had one of the worst winters ever this year here in S. Ontario. More people up here will definitely buy your product if they hear about it.

This is an excellent product. I replaced a Nutone roof vent with this one and the difference is amazing. I own apartments, and will be replacing the old ones with this one.

This vent saved my son a ton of money. He would have had to run too long of a vent pipe had this option not been available. It works perfectly and was easy to install.

Tile Roof Install
I purchased the gooseneck version as recommended for a tile roof installation, however I should have purchased the standard version. To meet code flashing must be installed on top of the roofing paper and on top of the tile - effectively two layers of flashing. To achieve this the roofer builds a small wood frame and installs flashing at the paper level, and then mounts the vent on top of the box at the tile level. Overall the installation still looks clean and doesn't protrude as much as you might think. Because of the installation method I could have used the standard profile vent, not the gooseneck. The vent works as advertised. The LG gas dryer I have has a "flow sense" feature that indicates there is no restrictions in the vent (20' run w/ two 45 bends). Overall I'm pleased with the product and have recommended it to both my roofer and my HVAC contractors.

Best dryer roof vent ever!
Very well designed product that works exactly as advertised. Low restriction but has a great back draft damper and no screen to clog with lint.

In-O-Vate Dryer Jack 486 Extra Clearance Roof Vent
Since purchasing our home over 13 years ago, we have had certain 'issues' with our dryer vent which vents through the roof. When we purchased a new, efficient front loader washer & dryer, I thought certain aspects would be 'better'. I was wrong. When we had our roof replaced about 3 years ago, I discussed with the roofing company, the issues that I had with the dryer vent - which entailed going on the roof for 2 reasons: 1 - to clear the lint off of the screen - which had to be done on a very regular basis; 2 - to clear the snow away in the winter so that I could use my dryer. The roofing company said that there were no better options, so for the past 3 years (since replacing our roof), either me or my husband have still had to go up on the roof to clear the screen on a regular basis; and to clear the snow when needed in the winter. I found your In-O-Vate 486 Dryer Vent Extra Clearance Model on line. My husband felt it looked to be a good product and we purchased it. Our roofing company was not terribly cooperative in replacing it; so we had our chimney professional do the work. Your vent is awesome. -First, no more clearing the screen - because there is none and we have since found out that a screen on a dryer vent is a fire hazard! The damper on the DryerJack opens when in use and closes when idle to keep out pests. I do hope that the damper door works properly for years to come. -Second, we had quite a bit of snow several weeks back, and the height and shape of the vent worked as we had hoped - we did not have to go on the roof to clear snow - the vent worked and cleared its own area - yea! I can supply pictures if you are interested. -Finally - a real surprising and huge plus - my dryer has never worked so efficiently. My dryer dries twice as fast as it ever has! I am guessing that the airflow is so much better. I am thrilled with the DryerJack Innovate Goose Neck 486 Dryer Vent. I wish that roofers cared about the products that they consider 'ancillary' to installing a roof. Your vent was no more money than the vent that they purchased from a large retail store; yet, your vent works properly and efficiently. Thank you for a great product! And - BTW, I am very happy to see that it is made in the USA! Sincerely, Barbara in New Jersey PS - The owner of roofing company came out and looked at our new DryerJack vent - and he was impressed.
