Questions and Answers
Q: In a 2x4 wall do you have to reduce vent to 3" pipe to stay in wall cavity?
Asked by:  - 5/14/2015 (Submit an answer)
A: Current codes allow for the 4" pipe to be squeezed or deformed to fit in the 3.5 inches of a 2x4 wall. Future codes though will disallow the deformation of the round pipe. Stick with 4 inch pipe. Dryer venting does not allow 3" piping.

Q: I am going to install this box do i need to install 5/8 type x drywall behind it and on the bottom and sides of this box? back of wall all ready has 5/8 drywall.Thanks
Asked by:  - 7/23/2015 (Submit an answer)
A: For multifamily, where there is a one hour rating required, the two layers of X board behind the box is required. More information on the one hour at this link:

If you are asking about a residential application, the one hour does not apply in most cases.

remodel use
I "found" this item through a contractor's trade magazine. I have completely renovated an 18-year old condo and decided to add the dryer box since I was adding a laundry box as well. It worked out pretty good but there were some issues since it's a remodel and water and gas were in the same area which made it "challenging" to get everything to fit. Maybe some re-design for such future projects would be in order?

Model 3D Dryerbox
Product shipped quickly and came packaged well. I used in a small closet for a stacked washer/dryer and it saved the space that I needed. Great product!

Great solution to small space
Using the 3D Dryerbox reclaimed enough space in the laundry closet for the new dryer. Installing the box was easy, cutting a new hole though the floor, less easy. Eliminating 3 elbows and replacing the 4th with a long turn elbow from Dryerbox made a HUGE difference in air flow. Well worth the effort!

Dryerbox
Great product, fit perfect. Could not find a down flow in any of the big box stores only plastic up flow units that were the same price as this metal product.

Perfect!
I looked and looked for a metal in-wall box that would vent through the crawlspace. This product is well-designed and well-made! I am pleased that I could add a full 4-5 inches to my laundry room, just by installing this box and getting my dryer up against the wall!

Works great after modified
I needed the downbox 2x4 box for my project. I cut out then smoothed out the holes so the down vent would be on the bottom right and gas on the top left. I had to flip flop my front loading machines so the doors would open outward properly. All plumbing and electrical had to be moved. It's finally done and works great. Now it's time for drywall.

Could not use
This was not a new job, but a retrofit; in any case due to framing and plumbing constraints I could not use the 3D. ( I modified drier to a side vent where there was room for duct work.) please note that retrofit models would not have worked here either. I hope that we can use it next year at my daughter's new house. I would like to point out that with the hole in this model fixed it does limit where it can be used. An option for a hole on either side would provide benefits. Otherwise, the construction is very good; I would recommend it.
