With the screening tool place the wheel towards the outside of the spline and start rolling it in that way if you slip the wheel of the tool will jump on the outside of the screen instead on top of your new screening.
Andersen window screen metal spline.
First roll in the wire on one side of the screen frame that will make an indent so you can place the spline in position.
Any suggestions as to removing carefully or replacing with a similar product.
A quick learner from jamestown ri says.
The spline is white aluminum square stock.
I asked at a home center and they suggested replacing with foam spline but the white square spline shows from the outside.
The screen rolling tool you have should be fine to use.
