Metal Door Draft Stopper, 36 Inch Under Door Sweep Bottom Blocker with Rubber Seal Strip, Aluminum Sweeps for Home Doors Rodent Proof, Brown

Best purchase. I dont know why but there was a mouse that digged its way in when I had the plastic version of this installed and that happened twice. This definitely won't let any mice through and I have no complaints with it. If you want to keep those pesky rodents away this will definitely do the job.

Keeps mice , bugs and dust from coming in. Cut with hacksaw for a 32" door. One star off for not receiving screws in shipment.

I have an external door that has a large gap at the bottom. The previous door sweeps we've installed would cover the gap but they were made of mostly rubber and outside rodents would easily chew their way through. This door sweep is mostly metal and covers the gap with it. The rubber portion is very minimal at the bottom and not enough to allow rodents to chew their way through. It was also easy to cut. I removed my old door sweep and used it to measure this one. Then I used a very small hacksaw to cut it, which took about 10 minutes. Two tips: use vice grips or something to hold it to a table and remove the sticky portion from the area you are cutting away otherwise the blade starts to collect all the gluey stuff making it tougher to cut.

Our garage door to the outside had a similar strip, but over time it had weakened, and we were concerned cold/hot air and/or mice might be able to get into the garage under the door. I bought this, cut it to the right length and installed it on the door so it blocked that area under the door. It seems to be working great.

Great
