HOMOTEK 8 Pack Hinge Pin Black Door Stopper,Adjustable Deluxe Heavy Duty Door Stopper 2-1/2"x1-3/4”,with Black Rubber Bumper Tips

With nothing to limit its range of motion, a door can swing too far open and damage the wall beside it all too easily. For lightweight interior doors,a
hinge-pin door stop can solve this problem with minimal time and effort. This device installs into the hinge assembly for the door and prevents the door
from opening far enough to bash into the neighboring wall. There is no need to buy door knob pads or loud spring door stops, these hinge pin door stops are all that you need!

Steps
1. Close the door. Slide the tip of a straight-slot screwdriver under the head of the hinge pin on the door's upper hinge. Pry the hinge pin up and remove it.
If necessary, tap the screwdriver gently with a hammer to lever the pin up.
2. Insert the hinge pin into the hole in the stopper assembly from above, so that the shank of the pin extends below the assembly. Slide the pin back into
the hinge. This leaves the stopper assembly resting on top of the hinge and the pin holding it in place. Tap the pin gently with the hammer to settle it into the hinge if necessary.
3. Turn the threaded screw attached to the rubber bumper by hand to adjust the door's maximum angle of swing. The more you turn the screw, the sooner
the stopper halts the door. Open the door to test the setting, and readjust it as necessary until the door stops where you want it to.

Things You Will Need
Straight-slot screwdriver
Hammer

Tips
For heavier doors, a fixed-post door stop is often a more reliable option. These screw into baseboards and block doors from opening fully.
Alternatively, install hinge pin stops in both hinges instead of only the top hinge.

Warning
Don't set the door's maximum angle of travel to less than 90 degrees.
