Anderson Window Screen Spline



We have several new replacement windows made by Anderson. Two of the screens were recently torn by our new dog. The spline is white aluminum square stock. I can not think of a way to remove it without twisting and/or bending it too much to reuse. I asked at a home center and they suggested replacing with foam spline but the white square spline shows from the outside. Any suggestions as to removing carefully or replacing with a similar product?

Hi Jill;

I have 0.270 inch diameter black polyfoam spline which would work fine to replace this but as you say its not going to match the original white spline. You could flip the screens around so the white frame still shows on the outside.

Re-use Anderson metal spline
by: Douglas Graham

You can make a simple tool to remove the metal spline on Anderson screens without bending it.

Take a piece of plastic tubing about 1-1/2 inch to 2" in diameter and about 12-15" long. Make a cut about 3/8" deep about 2" from one end, angled toward the near end at about 45 degrees. Starting about 2-3" from this cut, make a shallow angled cut, meeting the first cut. This removes a wedge shaped piece of the tube, making a shape like a shark mouth. Bend the tube into a shallow curve, with the "mouth" on the outside of the curve. Heating the tube may help.

Pry up an end of the aluminum spline. Be careful not to kink it. You just need enough up out of the groove to slide into the opening of your plastic tube remover tool.

Now just slide your tool along, and the spline will come out with only a gentle curve and no kinks.
