Features 5
- Garage Door Threshold Seal with Sealant Included: This 16 ft garage door threshold seal comes with 2 x 10oz building sealant for floor-mounted installation. Designed to help seal the gap between the garage door bottom and concrete floor while reducing water, dust, leaves, and drafts.
- Measure Before Ordering: The garage threshold seal strip measures 3.5 in wide, and 1/2 in high. It can be trimmed to fit smaller openings. Please measure your garage opening width and door clearance before purchase to ensure the 1/2 in height works for your door.
- Helps Block Water and Debris: The floor-mounted garage threshold water barrier helps reduce wind-driven rain, snow, dust, leaves, and drafts from entering the garage when properly installed on a clean, dry concrete floor with the included sealant.
- Durable EPDM Rubber with Serrated Base: Made from flexible EPDM rubber to withstand daily vehicle traffic and changing weather. The serrated groove base creates more bonding surface for sealant, helping the threshold stay in place after proper installation.
- DIY-Friendly Installation: Clean and dry the concrete floor, test-fit the threshold, cut to length if needed, apply the included building sealant, press the strip into place, and allow it to cure. Best for smooth concrete floors; not recommended for asphalt, oily, wet, heavily coated, damaged, or very uneven surfaces.
Description
When properly installed with the included sealant, the threshold helps reduce water, wind-driven rain, snow, dust, leaves, and debris from entering through the garage door bottom gap. The grooved base increases the bonding surface between the threshold seal and adhesive, helping reduce shifting after proper installation on a clean, dry concrete floor. Made from flexible EPDM rubber, the garage door threshold seal is built to withstand daily vehicle traffic, changing weather, and temperature fluctuations. The seal can be trimmed to fit your garage opening. Clean and dry the floor, test-fit the threshold, apply the included adhesive, press firmly into place, and allow the adhesive to cure before driving over it.

Stopped water and spiders from entering!
Color: Black
Size: 20 Feet
Purchase property that didn’t have door seals so we purchased this product to try because garage company quoted 4x price. It’s durable, tough, easy to install and stays in place. Replaced glue to shop seal after three years. Would definitely recommend and purchase again.

Keep Water, Bugs and Dust Out
Color: Gray
Size: 16.5 Feet
A nice piece for installing across garage threshold. Has provided a great seal for the bottom of the garage door. Gave a 4 due to the adhesive they use which is thin and black in color. Any mistake shows and it is hard to clean the adhesive up. With this adhesive I would recommend two people to place the seal.

Decent product and good value.
Color: Gray
Size: 20 Feet
I bought this to supliment my existing garage door seal to prevent water introduction during heavy rains. Well as things go...no rain since the installation!! The instsll was very easy for me. Following the instructions to the tee. Very important to clean concrete before you install. This product has an inside and outside facing so be mindful of this. Also important is the pre-install marking. Lay out with the garage door down on the product...a warm day is best....align and mark the floor (i used a black sharpie). Then open the door and carefully mark the outside. Solid lines are best - not dash marks every foot or so. You then have 2 parallel lines about 41/2" apart. I used the black adhesive sealant provided ( 16' door used only 3/4 of one tube) but in retrospect I might suggest a big box equal in gray to match product color and concrete color. That said if you apply the sealant provided ...hold back at least 3/4" from your parallel lines and keep the thickest line of sealant in the center. I applied 2 parallel lines about 3/4" from the edge abd squiggly lines od sealant in-between. I rolled up the product after cutting it to size. Measure 3 times cut once!! Then slowly un-rolled it carefully keeping it aligned between my lines. Used my foot to press down firmly. Then closed the garage door (I did this several times when aligning...before sealant is applied) and made final adjustments when sealant was fresh. After that...left the garage door closed for 2 days. All this took about 30 minutes from start to finish. Very pleased so far. No visible light coming from underneath. Original garage door seal is still on the door too. So I believe the will mean no water and no critters.

Prevents water seeping out the door way when mopping.
Color: Black
Size: 10 Feet
This strip is perfect for my church's kitchen entry/exit doors where water can flow out to the hall way making it dangerous for people slipping. It prevents the water seeping out when mopping the floor. Great product.

You get what you pay for
Color: Gray
Size: 10 Feet
The threshold seal itself seemed fine, but my 3 stars comes from the included adhesive. Application started off well however about half way through the caulking gun plunger pushed through the tube and lots of the adhesive came out backwards and covered the plunger and associated pieces of the gun. I suppose you get what you pay for, but the hassle of cleaning that up would probably just have me opt to purchase an extra known reputable adhesive tube next time.
