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.

  • Saves time, labor, energy, and money with all the innovations SPEEDI-COLLAR has to offer
  • Damper ratchet system allows you to adjust damper into 6 different positions for optimal balancing
  • SPEEDI-COLLAR features an integral gasket, a ¾ in. wide flange and quick-zips for an air-tight connection
  • SPEEDI-COLLAR is molded from high density, UV resistant resin making it durable, lightweight, dent and rust-proof
  • SPEEDI-COLLAR is fire rated for use in a plenum UL2043 classified

Rated 4.6 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by This product should be stocked in stores. This is a well engineered product. Easy to install. September 15, 2015
Rated 5.0 out of 5.0 by Easy to use, very functiional Just the item for an easy fix. Needed to add a short return air duct to a finished basement, and wanted to be able to adjust or turn off air flow as needed. October 3, 2013
Rated 5.0 out of 5.0 by Fits the bill, great price, easy install I slapped this collar into my vent system in a few minutes. The zip ties and adhesive collar made a good tight fit and I added some mud just be sure it was completely sealed. The damper has notches for each position so it doesn't turn real easily. This wasn't ideal for my application but a bit of shaving and sanding make it swing freely. August 5, 2014
Rated 5.0 out of 5.0 by Superb quality and very easy to install Superb quality and very easy to install. Just a great well thought out product. Absolutey seals up and is obviously not going to let any air leak out of it. Good thick quality plastic too. I am glad I purchased this instead of trying to become an HVAC expert and spending the money on tools etc. Incredibly the box arrived in a DAY! I am not kidding! Heck, even the packaging was incredible! it appears they used specially punched/cut cardboard from old boxes for the padding that seemed to make the cardboard into a thick flexible padding mat... never seen that before but the wife and I liked it a lot! way better than Styrofoam or messy peanuts. We have kept it and plan on using it for packing away our own stuff. November 29, 2011
Rated 2.0 out of 5.0 by Poor Design This is a good concept, but you will still have to seal the supposedly gasket and the handle for the damper sits to low to the housing. Once you zip tie the flex duct it's so far under the insulation that you can't even get to it. i had to foil tape and mastic every one of these, buyer beware December 17, 2013
Rated 4.0 out of 5.0 by Item functioned well for the use intended. Used the start collar with damper in connection with the furnace humidifier. The humidifier did not have a damper to control or close off air flow. I was concerned the plastic might crack during installation but it held up well. March 19, 2013
Rated 5.0 out of 5.0 by This product is the best HVAC take-off collar I have found. I wanted a bottom take off collar with a manual damper to run an HVAC dust into a gameroom bathroom register. I also wanted a collar that was easy to install without mounting tabs and with a good seal to eliminate leaks. This is a perfect selection for my application. July 10, 2011
Rated 5.0 out of 5.0 by Does exactly what I needed Good product had a hard time finding a damper for my Hvac system. Works perfectly and would buy again. April 24, 2012
