You’ve discovered a new addition to our dryer venting line.  This wall vent is unlike anything else on the market.  Having been in R & D for over a year, this vent features a powder coated galvanized metal frame and a lightweight damper that is innovatively impenetrable to birds and creates zero back pressure
Works great for new construction but was designed for ease in retrofitting the old inefficient legacy hooded vents.

Unlike legacy and “Mainstream” wall vents, our Dryer Wall Vent is without hesitation a "Premium" fitting.

Efficient: Without question, vent hood design or lack of, clearly remains the leading offender of inefficient back pressure levels in the dryers’ exhaust conduit.  Actual laboratory test best demonstrate the range of back pressure levels that popular wall vents create.  Values above .60 water column inch are considered in the industry as excessively restrictive.  Values below .20 water column inch are considered very efficient. 

The Dryer Wall Vent’s restriction coefficient is lower than any other wall vent we’ve tested. Less restriction in a dryer vent delivers real savings to your monthly energy bill.

Damper: Dryer vent hoods come in multiple styles.  The objective of a vent hood for the dryer is basically two fold; prevent back drafts and prevent bird or rodent entry as well as nest building.  We meet those objectives with a well-engineered lightweight damper that

• Mitigates the ability for a bird to open the damper
• Provides no Air-flow restriction
• And is easily accessible to duct cleaners

Design: The Dryer Wall Vent collar is sized to fit snuggly within the standard 4” seamed pipe.  This feature becomes an advantage to installers and DIY's when retrofitting this vent but also accommodates new construction.  Outside dimensions are 6.5" x 6.5".  

Material: Sun and weather take a toll on plastic vents, and the typical aluminum hooded vents dent and deform easily.  The stylish Dryer Wall Vent body is constructed out of Paint Grip (Bonderized) steel, then washed and powder coated to achieve an excessively weather tolerant and strong uni-body.  The securing screws are hidden behind the damper. 

The Dryer Wall Vent works with lap siding, stucco, brick and many other conventional sidings.  The non powder coated hinge pin is aluminum to offer total corrosion-free protection. 


Questions and Answers View all Q&A
Q: How well does this prevent back drafts? I have seen some with a rubber piece the door closes onto and this looks like metal on metal.
Asked by:  - 7/30/2014 (Submit an answer)
A: The damper has a few features that keep the rodents out and the wind from creating a nuisance. First off the damper has a small return of material around the three edges, this makes it almost impossible for a squirrels finger nails to get anything to grip on to open it, as well as a bird beak. There are two small magnets in each corner of the damper that creates a slight hold on the door to hold the door closed when it is not in operation, and this minimized the chance that the damper could "bang" in the wind. There are also two rubber bumpers that the damper rests on and also minimizes any sound it could produce by closing.

Q: Is the dryer wall vent paintable? If so, what paint do you recommend?
Asked by:  - 11/22/2014 (Submit an answer)
A: The finish on the wall vent is similar to what is on your washer and dryer now. if it was properly cleaned and roughed up with 220 grit sand paper, the vent could be spray painted with several very light coats of paint.

Not your typical dryer vent
This is a solid product with a nice paint job and finish. This is nothing like you typically find at "big box" or hardware stores. Installation was easy. I have had the vent for only a few weeks. Looks like it should hold up to the sun, wind and weather.

Ingenious idea!
Looked at lots of options to close off vent no longer being used due to design of new appliances. This was a fabulous solution! Clean looking, easy to use, keeps critters out, and should we ever sell the house, this would work for any new owner who wanted to "open" it back up for their use. Win-win!

High-quality, rigid, well-engineered wall vent solution sold at a reasonable price
My neighbor recently installed one in his home and I was very impressed with the difference it made over the original sheet metal aluminum vents that were installed when these homes were built. The cheap, sheet metal vents were installed such that there was only a very small opening between the vent and the outer wall surface, creating an annoying whining noise whenever a dryer was being used (you can hear them all whining down the block). Problem solved with the dryer wall vent from DryerBox. So when it came time to replace our dryer unit last month, I upgraded to this wall vent as well. The metal frame is very rigid and attractively finished with powder coat, the unit is easy to install, and is actually fun to watch in action when the positive pressure from the dryer exhaust gently lifts the damper. I am very satisfied with this product and feel that it is a quality, affordable upgrade to our home.

Excellent dryer vent
I bought this vent in Dec 2014 and have had it installed since January. It works great and provides an excellent looking vent compared to the cheap plastic or metal vents from the big box stores. I installed this on a older home that did not have a dryer vent at all. It was easy to install. I like the sturdy construction. This vent faces the eastern sun on my house and takes the beating from the weather. I wanted a vent that could withstand the weather. It opens and closes just as advertised. I have an eight foot dryer vent run with two elbows and it still opens up more than enough force. It stays closed and nothing gets into the vent pipe.

Nice Product!
Used this product to replace an existing dryer vent and existing bathroom fan vent. They have now been installed and both work great and look great. Can't speak highly enough about the nice finish and great design of these vents. Highly recommend this product! Note: I also installed a new bathroom fan at the same time. It is rated at 80 cfms and that was plenty enough to open this vent (probably to around a 30 degree angle when the fan was on). But if you are trying to vent one of those older cheapie bathroom fans that only pushes 50 cfms, I don't think that would be enough air to move the vent. So I think anything above say 70 cfms or higher for a bathroom fan would be enough for this product to operate properly. Caveat emptor!
