Customer Reviews for DuraVent DuraPlus 6 in. x 14.25 in Square Ceiling Support Box and Trim Collar 24 in. Tall

I installed this ceiling support box when I did an extension on our livingroom. It was easy to install and exactly what I needed for our cathedral ceilings. I have tripple wall S/S Duravint chimney from the inside of the box and up 6'. I'm using Duravent single-wall telescoping pipe from the ceiling box down to my Englander NC-30 wood burning stove (using the Duravent adapter at the stove). It all went together easily and I am enjoying a nice warm fire as a type this review and waiting for the concrete to cure before installing the flooring..

Before beginning, readers should know that this is the first such project I have done so I am an amateur. That said, I have done moderately complex renovations for many years and I found this support box had a really fatal flaw. The flange in the bottom which receives the top piece of stove pipe from the stove is a friction fit and does not extend below the surface of the box. As a result, you cannot secure the pipe section with keeper screws and must rely upon the friction holding the section in place. Since pipe sections are almost always out of round no matter what you do to true them up, slipping it onto the flange is a near impossibility from below, especially if you have no help (which I did not). Ultimately, I had to snip the flange with tin snips and banana-peel the petals slightly inward. After 6 hours of McGivering a number of attempted solutions only to have the section fall off when I let go, I was ready to give up when at last I jammed the section on hard enough that it held in place. I quickly slipped on the lower section and placed the stove under that to support the whole thing (the pipe sections were telescoping) and keeper-screwed the sections in place. All is solid and vertical now. I only recommend the product because It does look nice now and I may not have known what I should have done differently.

Fit nicely, works great.

Bought another size, will be returning

Did not fit - returning today

Quality product - wish I had known it only accepted DuraVent insullated pipe but used an adaptor. The description states 18.25" when in fact it is 14.25

Worked well, fairly easy to install.

There are no instruction on how to connect the stove pipe adapter to the ceiling support box!

Excellent service thank you

WORKED JUST RIGHT.

Easy to install.Good quality product.

I expected more robust box, this system is just empty and the pipe runs in to the bottom.
