The Draw Collar

This Draw Collar is used for wood burning stoves. It is designed to eliminate backdraft and draw problems, giving you peace of mind.

The Draw Collar for wood burning stoves is installed on top of the stove and the stove pipe is installed into the top of the Draw Collar.

This Draw Collar will work with single wall and double walled stove pipe and will not change any of the clearances specified by the stove manufacturer.

Simply plug in the Draw Collar and it will begin generating over 600 degrees of heat into the chimney liner. This creates a barrier that prevents cold air from dropping into the home through the wood stove-resulting in fewer cold spots in your home! This also creates the initial draw - no more struggling to heat up your flue to avoid smoke puffing back into your home on start up.

The draw collar for wood burning stoves comes with a thermal sensor regulator that allows the unit to turn on and off when optimal temperatures are reached, saving you power.

Enjoy peace of mind knowing any backdrafting-either on start up or die down-is no longer a worry!

500 Watts 120 V 3.8Amps

Includes a 3′ high temperature power cord with a 3' standard cord extension. 

Models available to fit on 6", 7", or 8" stove pipe. Please specify size when ordering.

We offer a satisfaction guarantee warranty which can be found on the shipping and returns policy page.

Your draw collar has worked exceptionally well, especially when used with our prior Vermont intrepid II stove. The issue with that stove is the poor design of the chambers that inhibit the stove to pull properly.

With our external stone chimney the draw collar is exactly what was need to preheat everything so we get less or zero reverse draft. No more smoke filled rooms!

We have found that the only time we need to use the collar with the Oslo F500v3 is if we are starting a cold stove. With this new stove we are getting seven to ten hour burn times so very rarely is the stove cooling down.

With that said, I wouldnt even think of having a wood stove without one of your draw collar’s installed on it.

You have designed a bullet proof product that you can be very proud of.

Hope this information has been of help!

God bless and hope your business is doing well.

It has worked wonders for us. We went from constantly struggling with the stove (flooding the house with smoke on several occasions) to having a completely predictable draft. I was worried about buying something that wouldn’t work, and luckily that was not a problem. This solution is certainly far more affordable than the alternative, which would have been adding length to our chimney to the tune of $10,000 or more.


Since we have installed the draw collar, no problems. No more reversed flue. No more smoke rolling out of the front of the furnace in the middle of the night. Most importantly, better sleep without worrying about the house filling with smoke.
After 4 years, and, a mistake on my behalf, i believe, i found this fall that the heating element in my Draw Collar was burned out. I always unplug it when the heating season is over, but, had forgotten this year. Thankfully, with the help of John, I was able to purchase a new element and sensor, and have it delivered to my home, for a very reasonable price.
Now my furnace is back up and running, and, I will definitely be happy to promote the Draw Collar, and Stock Squared, as i firmly believe in their product, and, their excellent customer service.
Thank you.

Dear John,
I would like to thank you for producing what I consider to be the most revolutionary product for drafting a fireplace. I had contacted your company after seeing your product video on Youtube. I have been searching for solutions now for over a year since my neighbor placed large trees on our property line causing my terrible draft issues. I spent over $900.00 on various products (ie. chimney liner extension, fan draft inducer, Vacu Stack) to no avail and thought that I was simply destined to live with smoke filled rooms ..... until I got the Draw Collar. After placing the Draw Collar on my rear venting Jotul F3CB I could not be happier. I simply plug it in, let it warm up for 20 minutes and light my fire. I have not had any issues getting a good draft/fire going immediately WITHOUT ANY SMOKE!! Your product is well worth the money!! I was quite impressed with its construction design as well as the quality materials used in the product. Thank you again for solving my draft issue!! We could not be happier now that we can once again look forward to many warm evenings WITHOUT SMOKE!!

Very truly yours,



Hello John;
Here is the picture of my stove and outside chimney. The draw collar seems to be my answer and I do not even need to keep it plugged in for more than 1 hr a day. I do not plug it in at all unless I think the fire won't last the night or on start up I plug it in for an hour or so to get the flu moving.
Great invention you will sell lots.
