PRIME-LINE Make-2-Fit P 7516 0.120 In. x 25 foot, Black Spline (1 Roll)

the line is too thin,can not fit the groove well

I bought this spline when replacing the screen on a patio sliding screen door. Works as intended. I didn’t notice any obvious flaws or weak points in the spline during application. I also had a few feet left when done with the screen door which was nice, I’m saving it for when I redo a window.

I replaced the screen on one of my windows, as it had been torn by pets. This spline was perfect... it's a little thinner than the usual which was important because I was installing a thicker screening material in the door (which was advertised to withstand the abuse my cats give it). Worked perfectly and was a breeze to install in minutes.

good

I have found that the recommended spline diameter can sometimes result in a screen that, while it will hold, can easily be pushed out of the frame by hand. A thicker spline is a BIT more difficult to install with the tool - you need to stretch it out a bit and/or put more pressure on the tool. But the result will be a screen that holds firm and tight. When doing your screen, work on a level, flat surface. It helps to have someone aid in holding the screen at one end of the frame. Pull it so it is snug and without snags, but be careful not to stretch it with too much force. The screen can tear easily if you over-do it. Remember, too, that that the movement of the spline into the channel will take up some additional slack. The nice thing about re-screening, is that it is very forgiving. If you are not satisfied, carefully pull the spline out and give it a second try.
