Your right thumb should be pressed on the lower right hand side of the screen frame and then you can gently push the screen into the recess of the frame.
Once the screen and splint are placed, trim off the excess screen material and you are all set to go.

Take the new screen splint and use the concave wheel on the screen roller to push the splint into the channel of the frame, fitting over the screen.
With the help of the convex wheel, roll the tool over the screen so that it gets pushed into the channel of the frame.
The screen roller will have two wheels at each end: a concave wheel that has an inward groove on the edge, and a convex one that has a rounded edge.
Now roll the screen all the way over the frame and pull the screen tightly over it.
Use a utility knife to trim the length, again leaving 2 inches excess at each end of the frame.

If there is any debris or dirt in the channel, clear it out well before continuing to work.
A putty knife or a flat screwdriver to remove the old screen splint from the frame.
