4" Roof Cap for Dryer Venting - 22 041

Sturdy and easy to install

The flap has gaps on each side (almost a 1/4" each), and there's a sizeable gap on the bottom where the housing joins the plate. I realize that seam is left open to allow drainage of condensation, but it's a HUGE gap. This thing is going to be a big source of heat loss in the winter unless I close the duct from below. If they had extended the 4" tube to engage the flap, this would be a much better design.On the positive side, it's much freeer flowing than the cheap square vents, and not subject to clogging with lint. The higher profile of the gooseneck design is also less likely to form snow bridges in winter.

Our roofer used this vent. I have to unplug it every 2 years. The flapper inside, plus the mesh over the opening, catch too much dryer lint.

Best dryer vent ever!!!! Top notch construction. Couldn't be more pleased all the way around. Would buy again.

Installed to replace the junky unit that is the only one the local big box stores sell. That unit leaked (through the duct) due to poor design. Installation of this unit was easy and it has been on the roof for six+ months without any issue. Once i saw the far superior design of this unit it became obvious why the other one leaked.

I installed this about a year ago to vent my dryer through my roof. The product I received was exactly as described. Although I don't recall any installation instructions being included with the vent, basic knowledge of how to install a roof vent is all that was necessary to install it. Remember that if you vent your dryer through your roof, you will want to keep the ductwork as straight and as short as possible to minimize lint build-up. I recently climbed onto the roof to clean the vent cap, and while there was some normal buildup of lint after 1 year of heavy use, it wasn't sufficient to hinder the opening and closing of the damper. I would recommend this product if you need to vent your dryer through your roof.

The height of this roof cap above the roof is not that much and when we really get huge amounts of rain fall in a very short period of time (happens a lot in New Mexico), the water runoff next to this unit is not high enough for keep water from splashing into the vent. I really wish this type of cap was 4-6 inches taller in height.I do love the smooth operation of the door flap and the material that this unit is built out of.

Superb quality construction. Fair better than big box store standard dryer vent. Additional height is great for flat roof installation in Northeast where snow is plentiful.
