## Description

12'5"/3.8m Weather Defender® Original | Ultimate Garage Door Threshold Seal Kit with Adhesive & Garage Door Bottom Weather Stripping - desertcart.com

Review: Works great! - Garage is downhill so when it rains the driveway looks like a river. Used a good quality glue put down in an x pattern and straight lines on both edges. Also put new seal on bottom of garage door itself, they seal great!! Garage doesn't flood anymore.
Review: Really like this - While it comes with written instructions, I watched the installation video they posted here on desertcart within the product photos. It's a relatively easy installation process and that video is very clear on steps I needed to take. After taking measurements, I used a hack saw to cut and dry fit, then used the garage door to help me determine exactly where I wanted it installed. I then marked the concrete with a pencil per instructions. The adhesive is extremely thick. So the only challenging part of the installation was putting down the adhesive because I needed both hands of pressure on the caulk gun to squeeze it from the tube. Other than that, it's a really good solution. I did NOT have to adjust the garage door opener settings, specifically the travel distance setting. It just works fine as it was.

*by S***5 on December 10, 2025*

I gave this product five stars because it fit and do exactly what I wanted, unfortunately the adhesive quality is a joke. The glue was hard; therefore, I recommend not to buy the adhesive, I'm asking for a refund.
