Step 1: Determine the distance between the door and the wall in the location where the spring stop is going to be installed. This should be while the door is in the most opened position, without the handle hitting the wall.
Step 2: Cut the spring stop to the distance previously calculated. A pair of strips, side cutters, or hacksaw are best used.
Step 3: Reinstall the rubber stopper on to the spring stop.
Step 4: Install the spring stop in the location determined, now your door will open fully. Top Notch!
