How to remove the 23-225

First, you will need to remove the door from the frame and place it on a stable surface. Once that's out, you will need to remove the screw holding the roller to the frame. All that's holding it in at that point are the hooks on the side. You will have to firmly but gently work the roller out until the hooks are free. I recommend using a pair of needle nose pliers to get a better grip as you do this.
