A self closing door hinges work an internal spring attached to the door and door frame. The hinges use spring tension to automatically close doors, rather than relying on the user to do it manually. You will see these hinges most often on the screen or storm doors that are installed in conjunction with a regular front or rear door. The tension of spring hinges should be straight to smooth and full closure, but if you notice that the door has problems closing too slowly, too fast or not far enough make some adjustments. Below are the materials and instructions for how to fix problems with self-closing door hinges.
Determine if you need to loosen or tighten the hinged spring tension by completely opening the door and closing it. As mentioned earlier, the door should be closed evenly and fully with a little noise. If the door closes quickly and with a bang, you need to loosen the hinged spring tension. If the door does not close completely, you need to increase the voltage. To tighten the hinged spring, first close the door. Insert a nail set on a hole located next to the locking pin in spring self closing door hinges adjustment. This hole is usually located either in the top or bottom of the hinged s house. Remove the locking pin by turning adjustment in the direction of the frame.
Then place the locking pin a hole closer to the door and release the spring pressure. Test the self closing door hinges at this time to see if it closes smoothly and fully. If it is still tight enough, just start over and move the lock pin further. To reduce tension, just follow the same procedures in the previous step, but instead of moving the lock pin to a hole closer to the door, place it a hole away from the door instead. In case of adjusting the voltage and lubricating the mechanisms do not solve your problems, consider replacing the spring completely. This is a good idea if you notice excessive rust or corrosion in the spring.
