They fit perfectly between my ceiling joists and look good with the return air grills on the room side that I also purchased from The Home Depot.

Rated 5 out of 5 by from Very impressed with the Quality I expected a simple flimsy register box and I would of been happy installing it. But these boxes made my job so much easier, solid heavy tin and straight- what more do you need? If you need a 12x12 register box don't hesitate to buy these.

Rated 5 out of 5 by from Greatly simplifies cold air return installation My biggest concern with the installation of new cold air returns in an attic above a downdraft furnace was the termination of the returns in the remote rooms. Building a register box from scratch struck me as fitting a square peg in a round hole. This product made all that headache go away. It is solidly constructed, has dimensions in line with specifications, and makes for trivial selection of filter grilles or other finish products as your preferences dictate. Highly recommended for anyone needing more cold air return capacity.
