0.140 in. x 100 ft. Black Spline

A:  Would refer to Screen Tight company at www.screentight.com. If this is the standard Screen Tight tracks the recommendation is .165 spline.

A:  The online table for the size of Spline is simply not correct.

A:  largest around .22 inches this spline fits this size channel so may be you can judge this link? if it works. http://www.homedepot.com/p/Saint-Gobain-ADFORS-5-16-in-x-84-in-White-Aluminum-Screen-Frame-Piece-FSP8491-U-FSP8491-U/100397093

A:  Get the roller tool to make the fit right

A:  Did you get the correct size? Also make sure you use the correct tool to push it into the channel

A:  Take a piece of the old spline with you to the store. Most HDs have many sizes.

A:  Well, the easiest way I've found has been to take a piece of the old spline with me, even if I have to rip one out of a screen, and visually compare it to the ones at the store. Be careful not to stretch the old spline when removing it and take strong reading glasses with you if you have myopia as I do. :-) The appropriate spline size can vary with the screen material being used because they too vary in thickness. For instance, I had to downsize my spline size on a screen door when I installed thick, pet screen rather than regular, insect screen. Are you sure it's the spline that's ripping the screen? I recently redid all my window screens with the Ultra Vue screen (love it!) from Phifer and found that it would easily tear if the spline tool went off track when installing or if the screen material was getting pulled too tight across the screen as I pushed the spline into the track. It was all me and my technique on a very thin screen material and not the size of the spline. We have a real tendency to try and stretch the screen material tightly which causes tearing at the spline or bending of the frames. Screens need to be a bit loose anyway to allow for expansion and contraction in changing temperatures. If you are having trouble at your local HD, visit another store that has more sizes in stock to determine the size. Or order a couple of sizes online and return the ones that won't work to your local HD.

A:  Look at online charts, frame thickness x width gives your spline diameter. 7/16x3/4 frame means I need a .135 dia. spline

A:  Take a piece of the old spline with you. Many HDs have several sizes of splines in stock.

A:  You can measure the channel with a tape measure get as close as you can to size. then start it and you can stretch it a bit then it will expand once you have installed it
