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

Did the job

Worked perfectly. Thank you.

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.

They come in a different sizes so measure first.Could be a litlle softer....

It worked on my Florida Lanai. It wasn't easy to install but it did the job.

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

It fit 👍 great

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.

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.
