350 Dryerbox

by Larry Jarrett| 11/14/2011 12:00:00 am

Worked perfectly. The dryer can be moved closer to the wall now and the ability to run my gas line to it is a great feature. Delivery was quick.

350 Install

My old dryer vent went through the floor, so I ordered this product, not really knowing at the time that it was designed for new construction. I have cabinets above my washer and dryer, so I removed the drywall from there down. Then for whatever holy reason I noticed that my 2x4 wall wasn't 2x4 at all, more like 1x3. After some magical structural refinement, my wall was back to 2x4, and installing this product was the easiest part of the entire project. Even after expanding the depth of the wall, we still saved room with this wonderful product.

I have used this box on a couple of occasions and prefer it over a plastic competitor version sold by some stores. Also, I want to say that the Dryerbox people provide excellent service and follow up.

Awesome dryer box

This box shipped quick and was easy to install

Could not be any happier, we managed to recoup wasted space that was occupied by the vent hose prior to the installation of the dryer vent box.

Love this product. It saved us inches in a very compact laundry room. Easy install and great service from the company. Will be using it for ALL my laundry room remodels in the future!!

Don't forget the Extras!

I like the dryer box, looks good, installs easily. Don't forget to order the other parts, the box does not come with any vent sections. you get exactly what you see in the picture. So order enough vent sections or plan on getting them in a hurry from Home Despot et al.

I am a contractor in southwest Ontario and have seen an ad for the dryerbox in my trade publications. I decided to use it for the first time in a basement apartment project. It worked very well at install stage and now that drywall is done it looks very neat and clean.

Easy to install - right solution

by David Weisser| 10/6/2011 12:00:00 am

Installing a new stackable washer/dryer in my walk in closet. Found the Dryerbox on line while doing some research on dryer venting. Attempted to get the product locally, but in the end I bought on the website. Convienent and fast delivery were great. Install was very easy and it looks great. I also purchased the 90 Degree Long-Turn Ell. Had a bit of a challenge getting it the ceiling the upstairs floor, but finally got it to fit right. Excellent product!

Great for snuggling up dryer right next to wall

by Lisa| 11/29/2011 12:00:00 am

If you don't want your appliances sticking out half a foot proud of your cabinets, then this is great. A little confusing is how it all fits together- you must use 4" rigid round ductwork (found at any big box) and squish it to fit in oval opening. The flexible ductwork is only for the dryer to rigid duct in dryer box. The gasline hole opening is also convenient.

Great Product

by Eric| 6/6/2015 12:00:00 am

Purchased this product to help fix the dryer vent that the previous owners of our house installed improperly. Came exactly as described and worked perfectly. Dryer now works great

great product

by Bob| 7/17/2014 12:00:00 am

Great product. Provides clear path for dryer vent so dryer can fit up close to the wall. As a builder I have installed on all our homes.

great product/ very good company to work with

by terri| 11/21/2015 12:00:00 am

The dryer box, a secondary lint trap and a roof vent were purchased from Dryerbox.com for a laundry room renovation project. I had questions with each product and found the staff to be very helpful and knowledgable. All the products were of excellent design and were manufactured well. Orders came in on time, well packaged and the contractors were impressed. It's all good… I highly reccommend this company.

Hi, Very pleased with both the service & the product. 9Model 350 dryerbox-2x4 wall. Thank you V.A.Searles


by Deborah Reno| 9/11/2011 12:00:00 am

I tried everything in the world to get this into a 2x4 framed wall. I couldn't get my pipe, which needed to be solid, formed to go through the oval hole and make a 90 degree bend outside. While it looks like something that would work great, I ended up not even using it. I will donate mine to Habitat.

Excellent product! Well made,comes with good installation instructions and looks a lot better than a piece of pipe stubbed out of the wall.

We have been using these dryer boxes for the past few years and have found them to be a perfect solution to a nagging construction problem. They provide a safer, more efficient, and better looking installation of your clothes dryer. Not only are these products well made, the customer service is also first class.

Worked out great!


by Larry| 8/15/2011 12:00:00 am

I am very happy and impressed with your products. I got a lot of comments from all of the different contractors on the quality and function. When I told them they were made here in the USA I got a few cheers. The home owners are very impressed and they have not used them yet Larry Curran.


by Scott Sheeler| 5/9/2011 12:00:00 am

Rick: The order arrived fast and n good order. I was really impressed with the sturdy nature of their construction - they're quite substantial and surprisingly heavy. I was more expecting a flimsy, tin box but instead received a tough-feeling box that will easily survive the rigors of the construction phase and provide a solid support for our dryer exhaust.

I've been purchasing the dryer boxes for over 4 years and use them on every new and remodel job that incorporates a laundry room. Along with the lint trap it's the only way to go! The pricing,selection,delivery and follow up are A-1! No need to shop elsewhere; I've always received products ordered quickly. This is the ONLY way to go!

Super Product

by michael| 6/9/2012 12:00:00 am

I was in a jamb when my wife wanted to move her laundry room from middle of home to the other side of home due to the construction of 2X4 walls. Everything from the box stores were for 2X6 walls until I found this site, The dryerbox saved me tons of time & money!!! Thank you much for inventing such a great product!
