RV Screen Removal:
The RV screen frame sides are exposed on the interior, while the top and bottom are held behind the RV or Motor Home window frame. Supporting the frame sides with the thumbs, lift the screen frame straight upward until the bottom clears the bottom of the window frame. Rotate the screen frame out of its opening. Working with the screen frame on a flat surface, loosen the screen spline at an end using long nose pliers. When the spline has been loosened, it can be pulled out intact. Be careful not to damage or sever it. The damaged screen mesh will then pull out easily.
RV New Screen Installation:
There is a tendency to spline screen in too tight, causing the sides to bow inward. Two ways to avoid this are: Order a complete new screen assembly, or block the inside edges of the frame with flat wood or metal strips nailed to the worktable surface, so that the screen frame sides remain parallel. Cut a piece of screen mesh about two inches larger than the maximum screened area. Center it over the area to be screened. Using the old spline and a narrow wheel screen roller, spline the screen into the screen frame. Keep adequate tension on the screen mesh as you go, but make sure not to cut the mesh with the roller. Do not stretch the spline. If the screen begins to bunch or distort, you can pull the spline out and start over, as long as you have not damaged the mesh. If possible, keep the screen mesh square in the frame. That is, do not let the weave of the mesh angle up on a side. After you are finished, check that the tension on the screen mesh is satisfactory. If otherwise OK, replace the screen into its channel by reversing the sequence above.
