P 7843 5/16 In. x 100 foot Black, Flat Screen Spline (1 Roll)

I bought this for kind of an odd purpose, but it turned out great. We have an older leanto greenhouse/sunroom we purchased many years ago. The frame is still good, but the top windows started popping out and I couldn't get them to stay in any longer, so I removed all the top and front windows. I covered the top with poly roofing sheets and added screen to the front windows.. There are grooves where the original windows fit, so I bought this hoping it could fit this in those grooves, keeping screen in place.. It works! I did the screens about 6 weeks ago, and all five windows are holding up very well. It appears to be good quality. I didn't have any problems inserting it. I used a window screen tool to roll it into the grooves. It cut easily with a pair of scissors.. I have gobs of it left, so I have plenty if I find another project to use it in.

A section of our patio screen pulled out during the last two hurricanes. I did some research and figured I could manage to fix it myself and save a few hundred dollars. I was right..really nothing to it after a quick learning curve. Watch some videos and buy quality tools (I'm sure I will need them again and it was still less money than paying someone). I could have reused the original spline, but I didn't want it to wiggle out again. I read the reviews on this product...they are spot on! What a pain to start the strip (even worse since I wasn't sure what I was doing). Do yourself a huge favor; set this stuff in the sun for a while before you start. What a difference!!! It got so much easier as it was hanging in the sun waiting for me. This is a nice big roll and I have plenty for future repairs. Fits into the Florida style patios perfectly. I also got the square plastic screen clips (only ones on Amazon) that a video suggested to hold the screen in place while working and really made the job easy overall.

it is perfect for screen cage spline replacement - works fine with screen or Florida glass. It is a bit of trick to put in. You need to put the top edge in first, and then use the screen tool and firmly press and roll until the spline is fully in the track...then do the long run. It will stretch/grow a bit as you move down the screen.

Very good, easy to use and not flimsy. This spline is very sturdy, used for linai around the pool.

Thank god for Amazon. This spleen cannot be found here in SWFL after Hurricane Ian. Came when they said and comes on a nice reel and works great. A little tip put the reel in the sun before installing to soften the spleen. Will buy more to keep for the next time I need to fix my pool lani screens.

After using the same type product from a big box store, I found this product slightly easier to work with. This one seems to be more rubberized and is slightly easier to work with than the other product which was stiffer and seemed more like a vinyl product. You can buy this product with confidence. The other product works, but is exhausting to work with. Four stars because I would like something a little more flexible. May be unrealistic, because this project was my first using this type of spline.

This appears to be a good quality product but there are mistakes in the description of the width.

Works just like it is supposed to if you know how to use it…there is a learning curve

Ordered this flat spline for screen replacement and it arrived one day after ordering and worked perfectly, soft and pliable rubber!

We ran out of spline and were in a pinch so though this would be worth a try. It's a much harder plastic and very difficult to use compared to the other brand we use. We won't use it again.
