Product Description

North Shore Commercial Door has garage door threshold weather seal kits in stock and available for fast shipping. These kits give your garage door a tight seal that helps keep water, dust, leaves and pollen out of the garage. These garage door thresholds have been driven-over tested and they will not crack or shatter. They will also remain flexible from 40 degrees below zero to 150 degrees, making this kit ideal for any climate. This threshold kit meets California Fire Marshall and CPAI-84 requirements for flame resistance and comes with a full two-year warranty.

You can purchase these kits in black or gray and North Shore Commercial Door sells these kits by the foot. If you order 16 feet for example, you will receive 16 feet.

COMMENT: I picked this item because water is coming in under my garage doors, it better help! by Jarred P 10/18/2014
QUESTION: Hello, if I have a 2 door garage and its 16ft, how much larger do i need to order it Will I have to adjust the garage door once its installed, so do I have to call a garage door installer to make sure the door closes by Jacqueline D 10/7/2014
ANSWER: The kit has to just fit the garage door. No adjustments needed for the door, just follow the instructions, The kit is not attached to the door. It is attached to the concrete. It acts as a threshold under the garage. You can also buy a rubber attachment to the garage door that would come down on the threshold. by Harold B a
ANSWER: Hello: Not sure your door same as mine, however I installed mine and made sure the seal extend to the length of the door opening which is a few inches beyond the door itself. If installed correctly it will not effect the door closing. I have had it for over a year and it stopped the water from coming in. not much heavy rains in LA by Denis D a
ANSWER: Measure exactly how long the opening is and order that amount. When I bought mine, it came in a 20 foot strip but I used the extra to weatherstrip under the door from the kitchen to the garage because it had a large gap under it that couldn't be fixed otherwise.<br /><br />I didn't have to call a garage door installer. My opener had a little adjusting slot on the side of the opener housing and I just adjusted it slightly to allow for the thresh hold. Since your car will be outside because you can't drive over the thresh hold for 24 hours at least, you should be able to reach your garage door opener quite easily as long as you have a step ladder. Don't waste your money on calling in an installer. If nothing else, look at the model of your garage door opener and look up the instructions on the internet for adjusting.<br /><br />I hope that this helps. I love my thresh hold. I have not had water intrusion into my garage since I installed it which used to happen every time it rained. by Debra F a
ANSWER: Hi Jacqueline, you won't need much more than the exact measurement of the door. My door did not require readjusting as the rubber under the door sat tightly on the rubber weatherseal. The weatherseal keeps so much dirt out now. by Victor M a

ANSWER: I have found with most adhesives using muriatic acid will clean oil<br />off concrete ok. Make sure you dilute the acid about 5 to 1 use<br />caution while using. <br />These thresholds are a great product, I have had excellent results. by Peter W a

QUESTION: We already have a seal on the bottom of our garage door that goes up and down with the garage door and is attached to the door. Would this seal call for adjusting the door or is it independent of the way the door closes Please respond at your soonest convenience. Thank you, Gilda by Gilda D 8/19/2014
ANSWER: If the bottom seal on the your is in good condition and makes even contact with little or no air gap,keep the existing seal. My door needed no adjustment. The threshold seal works even in a driving rain. I used a little more adhesive because my floor was uneven in a few places but make sure to follow the directions spending the time to mark the floor so that the seal is completely parallel with your door. by R H a
ANSWER: Yeah Gilda, you will more than likely have to adjust your down travel up a little to accommodate for the thickness of the threshold seal. by Jeff S a
ANSWER: I believe the door will close on one side of the threshold so it will not travel all the way to the floor bottom but the distance will not be that much different. Hope this helps. Curt by C W a
ANSWER: This seal is about 3/8" thick where the door makes contact...the height of the door will have to be adjusted so the door does not come down hard. I actually put this seal between where the vehicle is parked and the door going into the house..perpendicular to the garage door. It prevents water from flowing towards where we walk and our walk area stays dry. If used under the garage door there are things to consider. It will be difficult to sweep debris to the outside; it will be hard to sweep water to the outside from rain or melted snow. by W B a
ANSWER: In my case I did not have any adjustments. It depends, though, on how sensitive you have your door opener set. I suppose if it's too sensitive, your opener would reverse the operation. Even if it does, it's a very easy adjustment on your garage door opener. by Patrick D a
