## Description

M-D Building Products 03723 9 ft. Black Rubber Garage Door Bottom Seal - Pocket Door Hardware - desertcart.com

Review: Superb Rubber Garage Door Seal - This seal is 100% rubber, not plastic, so it conforms well to the space under the door. It is just the right thickness to give a stiffness so it doesn't feel flimsy, yet it can be easily handled for installation. The nails have a spiral along the shaft so they won't pull out as easily as smooth nails. The plastic "washers' have a large diameter that will keep the nails from tearing the seal. To cut the rubber seal to fit the door, a sharp pair of scissors works great. Installation can be done alone, but it goes more smoothly with two. Will know more in the winter if snow or ice will stick the seal to the cement, but the rubber's flexibility seems like it will keep that from happening. If this is not the case, I will update this post. The seal looks great on the door, making it look more finished, and we have already noticed it doesn't feel drafty in the garage anymore. We had a 1/8" gap below the door and this seal closes it perfectly. Our door is an "old fashioned" heavy manual lift type, and this seal also acts as a bumper to cushion the door when closing it, helping to protect the windowpanes. This seal is an excellent investment, will protect the door, and keep debris and animals out, and snow from blowing in. You will be pleased with this very high-quality garage door seal!
Review: Easy to Install Garage Door Seal - This garage door seal is very simple and quite effective. The seal is high quality with virtually no water retention. You will have to have your door in a partially open position to attach the strip. The product installs easily and comes with the required nails and they include plastic washers to increase the holding area. I had to purchase the 16 foot long sealer since they did not advertise a 10 foot long strip that I needed. The strip provides a very thorough seal should have a reasonably long life in outdoor conditions. I would purchase this again.

## Questions & Answers

**Q: how high is the vertical section between the door and the floor?**
A: The angled section ends about 5/8" below the bottom of the door.

**Q: I need more of the black "washers", but I can't seem to find any for #6 self-drilling screws that fit like these do?**
A: I don't know where you can get more washers but this is what I did. I used five washers from the old molding. You probably  can get washers from Home Depot. When the door is closed you can't really see the washers so it wasn't a problem for me. This is a great garage door sealer and easy to install. I hope this helps.

**Q: I have a metal garage door that has a bolt on bottom weather strip that is shot do you have a reasonibly priced replacement?**
A: You can use this on a metal garage door--we did, and it worked perfectly. You have to use self-tapping metal screws instead of the wood nails that are included. Capri Tools 10024 Hex Self Tapping Screw Assortment, 200-Piece, here on Amazon. The washers that come with this weather strip fit perfectly. This weather strip is just wonderful, and fits perfectly! It keeps out bugs, small animals, and the grass that the landscapers try to blow under our garage door after mowing!

**Q: Does anyone know what size sheet metal screws I need to order?**
A: The product camevwith nails. You do not need to order screws.

### ⭐⭐⭐⭐ Good looking replacement and a proper kit.
*by S***5 on December 8, 2024*

This M-D Building Products 03723 9 ft. Black Rubber Garage Door Bottom Seal was a good replacement for my worn out (as in torn up) garage door bottom seal. The seal itself is just a tad longer than 9 feet, so it is perfect for a 9 ft. door. The installation was easy, in particular, because it comes with the nails and plastic washers needed to attach the rubber strip to your garage door. One recommendation to the manufacturer would be to increase the nail/washer count by one so that the distance between nails is an easy 6 inches, and not some odd amount.
