This spline is just a tiny bit thicker than my previous order. The spline is not smooth but ribbed which is a good thing, less of a chance to come out of the channel. I would buy again.

The channel width of my frame is 4mm (or .155"). Seller says to use the same spline width as the channel width. The installation of the round .157" spline was super easy. Almost too easy. After I was done the screen seem to be holding. However, I was able to pull the screen free when I tug on a corner. While I had to tug fairly hard, I don't feel I tug as hard as the wind will blow. Anyway, ... time will tell. I'll give this a few weeks and then provide a follow up. I'm thinking about getting a thicker spline. [I tried to use a .321" flat spline, .. but couldn't get it to fit without damaging screen. Comments?]Follow up 10/6/24 - After 2 Hurricanes in OrlandoThe .155 diameter spline did NOT hold screen panels. I reinstalled the panels using a .188 diameter splien and so far, its worked great through 1 hurricane (Helena). So, bottom line I believe one should choose a spline width slightly bigger than the channel width. In my case, this was approximately .03".

Perfect. The one store in my area only sold one size and it was about a size down from this one. I am guessing that must be the usual size for windows. It worked great in our newer windows but not so much in our older ones. It was just a tiny bit too small and one of our screens kept falling out because if it. This one is the perfect fit. The quality is pretty much exactly what you would expect from screen spine. It works exactly as it should. The price is great too for what you get. I think the one in the store is little bit cheaper but it's not by much at all. I have no problems with this.
