- Measure the width of the seal as it lays flat. The most common widths are 3" and 4" (but could be anywhere from 2-1/2" to 4-1/2").


- Determine what "style" of seal it is. Probably the most common "style" is the T-style but there are also P-Bulb style, Bead style, T-Bulb style and others. On the T-style seal these are the parts of the seals that look like a "T" and slide into the bottom seal retainer. You'll want to measure these T's on the seal as this will determine which seal will fit into the bottom seal retainer. You're basically measuring the side of the seal. Write down your measurements. The most common "T" measurements are 1/4" and 5/16" but there could also be a similar 3/16" size. While a tape measure can be used to measure the "T" we have found a digital caliper to be the best way to measure the "T" so if you have a caliper we recommend using it to take the measurement.



- Difference between vinyl and rubber. The vinyl seal is going to be a little bit stiffer than the rubber seal. The rubber seal is going to be slightly better for extreme hot and cold temperatures. Both seals have ribs on the one side to help keep out the dust, dirt and water.
- Overall length of the seal. If you order seal from us then we will ship your seal with an extra 5" to 6". So if you order a 9' long piece of seal then the actual length of seal you get will approximately be 9'6". The extra seal is for tucking back into the retainer when you install it.

Hi. I have three 8’ foot garage doors and I’m trying to find the correct replacement bottom seals for them. They seem to be smaller than the common seals that I see on the website. The original seal for the channels seem to have a 3/16” slightly rounded top lip, but not quite a T. Naturally, the old ones are stiff and hardened, but are less than 2” for the bottom floor contact and has 7 ridges that run the 8’ length. Also, I live in S Fl and would like your suggestion for what material is best for sun and heat. Hope you have a product that would work. I can also be reached at (954) 796-8411 if I can answer any questions. Thanks

It doesn't sound like your doors use the 1/4" T-style seal that we sell. If you want to send us some pictures of your bottom seal that shows the part that slides into the seal retainer on the door then perhaps we can help you determine what type of seal you have. You can send your seal pics to us at [email protected]

If you are sure that you have a 1/4" T-style seal (and it's not 3/16" or 5/16" style) then you could use the 4" vinyl or rubber seal that we sell. If you're not positive if it's 1/4" T-style then you could get the Seal Sample Pack found here: https://www.garagedoorzone.com/SAMPLE-14-T-Bottom-Garage-Door-Seal-Sample-Pack_p_328.html You can use a sample piece of the seal to make sure that it fits your door before ordering a 16' piece of seal. You can also see & feel the difference of the vinyl and rubber seals.

I'm replacing the seal on a CHI 16 foot door. The one I have is 3 inches with a 1/4" T on the seal. I live in North Dakota so I think the rubber seal would be best given the harsh winters here. My question is can I install a 4 inch seal in the hopes the seal will extend out a little more to make up for a gap between parts of the door bottom and the concrete? Or will that not work at all? Thanks
