Prime-Line B 705 3/4 In. to 1-3/8 In. Wide, 7 foot, Black Vinyl Bug Seal (Single Pack)

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.

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.

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.

The original vinyl seal came apart after many years and needed to be replaced. This seal went right in and stays tight against the other door. I was thinking that I was going to have to cut it down somewhat and was surprised that it was exactly the proper size. Reason is that measuring needs to be done for the total width of the seal and not from the start of the insert. So measure from the surface to be sealed against clear out to the final edge of the seal channel in the door.

Product seems great. Nice and soft rubber. Seems real easy to install until you get to the end in the center of the roll. Spent to long trying to get that side to shove into slot. The outside end is nice and easygoing it once you start getting to the center of the coil it’s a real pain. I get trying to package things in small containers for many reasons but at the expense of destroying your product? I ended up cutting a small piece of leftover product to wedge it in maybe once the curls have relaxed I can try again to get it manipulated into shape in place.

This may be my first Amazon review. Even when products aren’t great, I typically don’t bother. But, I felt I needed to write this to help others avoid it. The first half of this roll was just fine. The second half was useless as the gasket part that gets pushed into the door was so compressed that there is no way to make a solid seal. This brand new stuff falls out easier than the 23 year old stuff it replaced. The first half of the roll was great and I thought it would be a great replacement. But, it’s literally useless and not worth the trouble of returning. But, stay away!

As advertised and easy to install. Fits perfectly.

This product fits better than the original, with admittedly some work planning best method of trimming. First lay flat in warm sun for an hour or so to soften vinyl and help reduce package folding kinks. The material does not tear as some suggest. Determine the exact amount to trim and use a straight edge as a guide to cut off with a fresh utility knife. Very pleased with the results!

This product does exactly as it’s suppose to do. I had a gap in my patio screen and mosquitoes would come in. Since installing (which was a breeze) we’ve had no issues. Thanks -great product!

It's hard to install but works well.

The Prime-Line B 705 fits a range of widths (3/4 in. to 1-3/8 in.), which makes it versatile for different sliding doors or windows. However, I found the build quality lacking—it felt flimsy and didn’t hold up well under regular use. The adjustment mechanism is functional but not smooth, and it can be tricky to get a secure fit. It might work for light-duty applications, but I wouldn’t recommend it for anything requiring long-term durability.
