Return Air Cans from The Duct Shop are the perfect fitting to use when you need to put a return air register in the wall or ceiling to return the air to your furnace. All Return Air Cans are manufactured from the highest of quality galvanized steel. Sizes listed are the box opening. The back of the cans are flat sheet metal for you to cut the desired size of return air duct into.
Installation Tip — Cut the proper size hole in the back of the return air can and install a Start Collar of the same size. Attach the return air can securely to the framing members with nails or screws. You may want to attach a 90 degree elbow to the round collar that you installed on the return air can and then attach your Flexible Duct or Sheet Metal Duct to the elbow. This will provide the best possible airflow for your systems efficiency. We recommend that you seal the seams with a duct sealant after installation to prevent any air leakage, increase the efficiency of your system and reduce your utility bills. See installation tip for Flexible Duct or Sheet Metal Duct, depending on which type you will be attaching to.
