Serrated (Ribbed) .225 foam screen spline is a type of material used in the construction and repair of window screens. It is a flexible strip made of foam material with a cross-sectional diameter of .225 inches, which makes it an ideal choice for securing the mesh material to the frame of a window screen. The spline is inserted into a groove in the frame and used to hold the mesh material in place, helping to maintain the structural integrity of the screen.

One of the benefits of using foam screen spline is its flexibility. Unlike other types of spline material, foam spline can easily bend and conform to the shape of the frame, making it easier to install and ensuring a tight, secure fit. Additionally, the foam material used in the spline provides a level of cushioning, which helps to absorb any impacts that may occur during normal use, reducing the risk of damage to the screen.

Overall, .225 foam screen spline is a durable and effective solution for securing window screen mesh material to the frame. It is commonly used in both residential and commercial applications and is an economical choice for repairing or replacing damaged screens.
