If you can remove the door go to step 2 figure 2.
How to install sliding screen door wheels.
Sliding screen door rollers are spring loaded with adjustment screws located over the wheel or inside the vertical frame.
Most screen doors use spring loaded rollers to keep the door from jumping off of the track.
Remove the screen door if you have one.
Over time screen doors become difficult to move along their track.
The increased difficulty occurs when the rollers installed on the screen door become worn rusted or caked with dirt.
If not please continue to step 1 figure 1.
When you open or close the door it doesn t actually slide.
First lift your door up and down in the track.
Make clockwise turns with a phillips screwdriver to push the wheel outward and raise the door or use counterclockwise turns to retract the wheel and lower the door.
Instead these wheels ride the track.
Grasp both sides of the frame and lift the door up off of its tracks.
Place the screen doors safely off to the side until you are ready to put them back.
