15 in. Ductboard Triangular Terminal Box is rated 4.4 out of 5 by 3.
Rated 3 out of 5 by from Not exactly what I expected. YOU MUST BUILD THIS YOURSELF - NOT ASSEMBLED ! ! ! I should have read the extremely fine details that were hidden from plain view. You must fold this box together and then tape it closed. I wouldn't usually complain about this, but I also had to cut down the inside of the bends as well. The angles were cut to be 90 degrees, not made for a triangle.
