Start Collars from The Duct Shop are an economical way for starting a new duct run from your supply or return plenum. They are manufactured from the highest quality galvanized sheet metal and to our exacting standards.
Installation Tip — First, you would cut the proper size hole into your plenum using sheet metal snips. Next, you would bend every other tab on the start collar out 90 degrees. Then you would insert the remaining straight tabs into the hole you just cut and then bend those tabs 90 degrees to the inside of the hole to hold the collar in place. No sheet metal screws are necessary with this application method. We do recommend that you seal around the connection from the start collar to the plenum with a duct sealer to prevent air leakage. Also see installation tip for Flexible Duct or Sheet Metal Duct, depending on which type you will be attaching to.
How to Install a Start Collar
by The Duct Shop
One of the first steps in running a new HVAC, heating or air conditioning duct is to install a Start Collar into the existing plenum or duct. In this article, The Duct Shop will explain how simple this process can be. After you have cut the proper size hole into your plenum using sheet metal snips, you need to bend every other tab on the start collar out 90 degrees. Then you would insert the remaining straight tabs into the hole you just cut and then bend those tabs 90 degrees to the inside of the hole to hold the collar in place. No sheet metal screws are necessary with this application method. It is that simple.
We do recommend that you seal around the connection from the start collar to the plenum with a duct sealer to prevent air leakage. This will help prevent air leakage and reduce your energy costs. With your Start Collar installed, you are now ready to attach the flex duct, fitting or galvanized duct to continue your new duct run. The Duct Shop has a full line of sheet metal ducts, fittings and accessories necessary to complete any HVAC project you may be undertaking. In addition to the extensive variety of in-stock items, we can also custom manufacture any size, shape or quantity of duct that you may require.
