Window Screen & Solar Screen Spline

Round Serrated Window and Solar Screen Spline

Often when you repair a screen you can reuse the old screen spline. Sometimes you cant because the old screen spline is in poor condition. Screen spline is a available in quite a variety of sizes. The sizes used depend on who the predominant supplier of windows was when most of the houses were built in your area and or who made the frame your using if making a new window screen. The .250 size replaces the 1/4" aluminum spline that was used in houses built in th e fifties and sixties. This size is particularily easy for the do it yourselfer to roll in. Other factors that determine size is the material you are replacing. If for example you are replacing a thin fiberglass insect screen with a thicker material like "pet scree" than you would use at least on size smaller than the current spline. So if your current screen spline measures to a .165 than with pet screen you would use a .150. Just remember that the screen material alone doent determine the proper size spline to use but the channel size and screen material selection do.
