Review: Huge improvement at little cost, but learn from my mistake - A couple of years ago I bought a beautiful home that was a bit of a fixer upper, not because it was run down, but because the previous owners had taken it upon themselves to add "improvements". One was cutting the bug seals away from the glass until they became useless. I never really gave it much thought, even though the house has spiders, until I saw a moth flutter in through a closed screen door. So I bought this for the upstairs. Holy smokes! I had no idea it would be so easy! If you are not sure if you should : a) buy this, b) call a handyman, or c) order a new screen, check your old stripping to see it if sits in a ridge in the screen and you can pry it out by wedging a screwdriver between the screen and the strip. If you can, skip the handyman. There is nothing simpler than this. But that's not to say foolproof. Here is my tale, which may explain some of the low reviews. I popped out the old one upstairs and put in the new one without cutting it. I simply pulled the old one out of the door, press the new one in to the slot, smoothed with my fingers until it was flat, then carefully trimmed off the excess length at the bottom. It worked like a dream! The black strip hung out more than I liked, so I figured I would order a new one for the downstairs and trim that one one notch. That was a mistake. I trimmed it one notch, which was super easy. I just cut along the line for one inch and then ripped it. Super simple. Then I installed it in the door. Oh dear. Cutting it was a mistake. You want too much and here is why. 1) These screen are never straight. While there is plenty at the top and bottom, in the middle, the edge I tore to fit is snug up against the glass. 2) When it is too snug against the glass and the frame, it sticks and bunches up when you open the door, causing the door to jam and the bug seal to pull right out of the track, unless you trim it away from the glass until bugs can get in, like the previous owners did... Trust me. You want that inch of flat black hanging over the glass and the frame. You will have no trouble if you leave it uncut. I've since replaced it and both work great. Oh, well. Lesson learned, for the price of a cup of coffee. Not bad considering the huge uptick in quality of life I am already experiencing.
Review: Works perfect! Awesome customer service! - What is this used for? Sometimes, a patio door has a gap between the doorframe and the screen door where bugs can easily sneak through. This product is a rubber piece that slides into a track on your sliding door and has a flap to seal that gap. The piece that fits into the track on the sliding door has some ribs that compress to allow you to push it into the door and allow it to stay. It was a little tricky figuring out which size to get because I didn't know how much the ribs compressed. I contacted the manufacturer, and they recommended getting the size that is slightly *larger* than the width of my track (because the ribs compress). My track was 5/16 inch (0.3125 in), and I ordered the 0.350 in product. It fit like a charm! It easily inserted into the door. I was then able to cut it to length with scissors. I did not need to adjust the size of the flap, but it looks like you can easily tear part of the flap off to get it to size. See the attached photos in case you are confused how this product works. Note: the photo showing the flap out of the channel is just to demonstrate how the product installs--it easily fits back in.

### ⭐⭐⭐⭐ Nice quality. would have worked great if size was correct.
*by C***S on October 5, 2025*

Didn't fit, but was easy to exchange. Most important to measure the thickness of your current nub that fits into the gutter on the door. This one was just a fraction of an inch too big. Wouldn't go into the gutter.
