I was worried at first about getting the 4" rigid pipe to fit in the 2x4" wall and also into the oval opening of the box. After reading all the instructions on this website, everything worked out fine. I got everything fitted & foil taped, connected the dryer, and it works perfect. The airflow is amazing, the LT90 seems to really make a difference (my run calculated out to 20' from the box).

The Dryerbox was the solution we needed. This product should be installed in every laundry room. The quality is good, the LT90 Elbow is nice. Everything was good, I was not dissapointed at all. It is working much better than the previous set up, the vent on the outside when the dryer is on is blowing wide open, no restrictions.

Nice product

This particular item is very useful in more ways than one, but we would like for you to come up with an attachment at the top for the 4" pipe to attach to instead of making the flex become oval shape to fit the rigid pipe coming through the top. Other than that it works good.
