Product Overview

SPEEDI-COLLAR is the innovative energy efficient and time saving Start Collar alternative you've been waiting for. This revolutionary start-collar features an adhesive gasket that attaches to duct board or metal trunk lines. The patented Quick-Zips tighten to create a virtually air tight seal. Therefore there are no added sealants that are required unlike a standard start-collar. The patented Quick-Zip mounting reduces installation time from 10 mins plus down to a minute or less. And if you pre-attach the flex duct, you can be out of the attic or crawl space in minutes, not hours. The collar was designed with the Quick-Zips located on the outside of the collar flange. You won't have to stick your hand inside a sharp metal collar ever again. There are no sharp tabs to bend back which take time and can cause serious painful injuries. It is the fastest way to connect duct to trunk lines or to the main HVAC unit. It is the "One Collar that Fits All". It can be used with 1 in., 1.5 in. and 2 in. duct board and zips tight or attach to sheet metal trunk lines with screws through the pre-drilled holes on the collar flange. You would need at least four different metal tab collars and have dozens of injury causing tabs to bend back to do the same thing. It can be used for Remodeling, Do it yourself, New Residential / Commercial HVAC projects. This SPEEDI-COLLAR comes with a preassembled damper that ratchets in place.

Exactly what we were looking for. Word of advise, the adhesive is nearly unremovable once it touches anything. Make sure you have the collar exactly where you want It before pulling off any backing.

Well made, easy to use.
Easy to use, great quality, fast delivery. Dampers are easy to adjust and pre-applied adhesive makes good seal to plenum.

Not a Gimmick!
I am an HVAC rookie, but was looking for a way to balance the hot side of the house with the cold side on the opposite end. I installed this at the origin of the duct to the hot side of the house. Installation was fast and easy. I was a bit nervous about using this product because of all the features like the adhesive gasket and plastic surround, but I found it to be much better quality than the standard all aluminum start collar/dampers. The damper fit was much tighter inside the duct, allowing tighter airflow control, than the standard collar/damper I also bought. Install took all of about 20 minutes and that is for a first-timer and taking my time. Don't forget to also purchase the large duct zip ties to secure the flexible duct to the collar.

Product exactly as described on webpage.
Product was easy to apply. I had to modify application since I set it up temporarily to confirm this non-standard application was functional. It has worked as intended after easily being installed.
