## Overview

The Prime-Line P 7843 is a 100-foot roll of UV-stabilized black vinyl flat screen spline, precisely sized at 5/16 inch wide by 0.092 inch tall. Designed for fiberglass mesh installation in aluminum frames, its flat bottom and curved top edge ensure a secure fit. Durable and easy to install, it pairs perfectly with the Prime-Line P 8228 rolling tool, making it a must-have for professional-grade window screen repairs and upgrades.

## Description

This flat screen spline is constructed of vinyl and comes black in color. The spline measures 5/16 inch (0.315 inch) wide x 0.092 inch tall x 100 ft. long and it is used for installing fiberglass screen mesh into aluminum screen frames. This type of screen spline is installed by laying it flat into the spline channel (over the fiberglass screen mesh) and inserting the inner edge of the screen spline under the lip of the screen frame. The spline can then be rolled in along the outer edge of the screen spline.

Review: I bought it to create screen windows in an old leanto greenhouse/sunroom. Worked 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.
Review: Save some money - 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 desertcart) that a video suggested to hold the screen in place while working and really made the job easy overall.

*by M***I on January 28, 2018*

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.
