The G-Floor Garage Door Threshold seal mounts directly to your garage floor creating a better seal for your door. The new tighter seal will help prevent anything from being blown under your door such as water, dirt, leaves and snow. In addition the seal helps reduce air drafts saving on energy costs throughout the year. The seal is attached directly to the floor creating a physical barrier preventing moisture from seeping in where there may be an uneven surface. The threshold is one solid piece of vinyl with no gaps or cracks so your barrier is solid. This product is compatible with all types of doors. One cartridge of adhesive included for mounting trim directly to floor.

  • 100% Polyvinyl threshold stands up to adverse weather conditions without peeling or cracking
  • Available in three sizes to fit your needs

Rated 4.6 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by Perfect As Intended! The Midnight Black (Garage) Door Threshold Trim is a first-rate and robust product. After delivery (rolled up in a box), it takes a bit of effort (not much) to flatten the roll (in order to facilitate installation and improve adhesion to the concrete garage floor.) Once straightened out, cut to size, its position marked, and installed, the threshold performs its intended purpose magnificently. Provided mounted with the appropriate adhesive, the quality of the material assures a long life, even after continuous car tire commotion. As no installation instructions accompanied this shipment (in our case), watching a few YouTube installation videos proved beneficial in determining the do’s and don’ts. December 10, 2013

Rated 4.0 out of 5.0 by This product is easy to install and easy to clean. However, it seems that stores have a limited supply. This product is easy to install and easy to clean. However, it seems that stores have a limited supply. January 30, 2013
Rated 4.0 out of 5.0 by Easy to install The trim was very easy to install, and works great. I was getting water seeping under the door due to a dip in the concrete. Two days after the install we got a blowing rain storm and didn't get a drop inside the garage. I would highly recommend unrolling the trim and laying it flat for a day or so before installing. It makes it go down nice and flat. November 4, 2014
Rated 5.0 out of 5.0 by Something I've been looking for, for 2 years. Finally! I found what I had been wanting. With very little roof overhang and concrete that has a dip next to the inside of the door, water had been going under the door and into the garage. Having to sweep it out after every rain had been a pain up to now. I cut the threshold material with a hacksaw to just a little over the width of the door. Using the included adhesive, I glued it to my concrete floor. No more puddles! April 22, 2014
