Product review (4 stars): Sheet metal build was ok
I bought it as a fix for a new dryer that did not fit in the existing enclosure. My existing vent came strait up through the floor. I thought I needed an extra inch to get the dryer pushed back so that the bi-fold doors would close.
I seemed to had gotten the inch once installed (not much more) but it was not enough. I ended up having to move the bi-fold  doors out an extra inch also.
Sheet metal build was ok but some of the joints were not tight and required tape.
