Amazon Customer: Used this to create a second seal on the inside of my garage doors. Blocks all the wind.

clibclib: Its Cheap material; definitely not rubber. My Garage door is an old wood door, double wide, it doesn't sit perfectly, although the resting place is a solid level cement threshold. Not what I needed, just too light weight and not bulky enough to fit tight.

I did however install it and used the best parts of my old rubber one to double up on the ends of the door where I had the biggest gaps. Pictured here is the old rubber one from my door; the bottom of my wooden door with no weather stripping and finally the method I used to keep this in place while I was working solo.
Even after doubling up I am still not pleased, but it is better than what I had with the old worn out one.

take a look at your door closely while in the down position; if it all looks perfectly square, then this might work, but if your door (especially a double door) has a center sag (normal) then you may have gaps on each side.

On a positive note, its plenty long for a 16 foot door, with some to spare; the tacs and built in washers are good and the washer combination should help keep the tacs from pulling right out of this poly material; plenty of these included.

JC: After trying to install a rubber seal which slots into a newly installed aluminum track, I discovered the door wouldn't close due to limited clearance at the top of the framing. I was looking for something less 'bulky', and this fit the bill. It seals the gap, and is both pliable, and seemingly durable. As others have said, the nails/plastic washers supplied are lightweight, and not suitable for installation. I bought some 1" galvanized roofing nails, and replaced the lightweight nails, using the plastic washers. Perfect!

AC: Product was a little over 16' maybe 16' 9" or so, which was nice to have some margin for error. I redid 2 8' doors that have not had their bottom seal replaced in at least a decade. This wasn't a heavy duty rubber, but wasn't foam either, so no idea how long it will hold up. Since I cut in half, the outer part of the roll was easy to deal with by myself. The inner part had a tight coil and wanted to wind back up, so I hung it up and put heavy clamps on the end as weight to straighten it out, which it did well enough. Not sure about longevity of the nails - they were painted not galvanized. I think these will out before the rubber does and then I'll replaced with galvanized roofing nails. Overall, not an amazing product, but a good value nonetheless. I could see light under the door without a seal, and none with them.

dan: Simple design. Easy to install. Cut to fit is easy to accomplish.
Good seal when new. Hope it stays flexible over time to maintain good seal.
Much less expensive than the round tubes that fit in a track.

Vanessa ~: Easy to install. However, if you have a gap between your garage door and ground level, don't expect this product will totally block the gap because the angle of the rubber is not really 90 degree but a bit bent only.

Rick K: PROS: The price is VERY cheap & is actually pretty wide (other reviews complained about this)

CONS: IF you actually use this as your only weather strip for the bottom of your garage door it provides little to no depth, thus water, wind, dirt, bugs and critters will still get in. Unless your garage floor is extremely level and your garage door is closed with downward & sustained force (not likely) there will be gaps.

The strip is made of a rubber "like" material that has an almost spongy feel to it. The supplied nails do NOT look like the picture, they include a black plastic type washer, because the nails along would rip through the rubber "like strip. NOTE that almost ALL garage door bottoms are metal these days - so the nail are useless.

I bought this NOT as a replacement for my current weather strip, but in the hopes of using a little of it as a CHEAP patch. I have a two car garage with a single door. On both ends there is a couple inch gap where my weather strip is short. It has been that way since I bought the house from the previous owner.

I live in Florida & the other day I heard my wife yell - a snake was in our garage! Snakes are...
