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. ## Features - Used for installing fiberglass screen mesh into aluminum screen frames - Extruded UV stabilized black vinyl - 5/16 inch (0.315) wide x 0.092 tall - 100 foot roll - Flat bottom and curved top edge - Use with Prime-Line part P 8228 flat spline rolling tool - Please refer to the line art drawing for dimensions and compare with your needs before ordering ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LGW4HFA | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #291,111 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #33 in Window Screen Splines | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (687) | | Date First Available | July 2, 2014 | | Included Components | Spline | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 2.42 pounds | | Item model number | P 7843 | | Manufacturer | Prime-Line Products | | Material | Vinyl | | Part Number | 8619496 | | Product Dimensions | 1200 x 0.31 x 0.31 inches | | Size | 0.185 in. | | Style | Spline | | Warranty Description | Goods are warranted against manufacturing defects for 1 year. | ## Images ![P 7843 5/16 In. x 100 foot Black, Flat Screen Spline (1 Roll) - Image 1](https://m.media-amazon.com/images/I/71Qd8mhKx9L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I bought it to create screen windows in an old leanto greenhouse/sunroom.

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. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/19481540-p-7843-5-16-in-x-100-foot-black-flat](https://www.desertcart.vu/products/19481540-p-7843-5-16-in-x-100-foot-black-flat) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-11*
