Interior door spring hinges use an integrated steel spring mechanism put under tension through the opening swing of the door and automatically return the door to a closed position by releasing the spring's tension. A spring hinge set too loose will not close the door completely. If set too tightly, it will overstress the spring mechanism and shorten the life of the hinge. Correct adjustment takes just a few minutes and ensures the door operates properly.

Open the door fully, then allow it to close by the action of the spring hinge. A properly adjusted spring hinge should close the door in a smooth motion and should fully engage the door latch in the strike plate. The spring hinge tension must be increased if the door fails to close completely or closes too slowly. The spring hinge tension must be decreased if the door closes too hard or fast.
Close the door to make all adjustments to the spring hinge.
Increase the spring tension by locating the spring hinge's adjustment ring at the top of the spring housing. Insert the tip of a nail set or awl into the open hole beside the locking pin and rotate the adjustment ring horizontally away from the door approximately ¼ turn to allow the locking pin to be removed and repositioned to the next hole toward the door. Release the pressure to allow the locking pin to rest against the stop.
Open the door and allow it to close. Repeat Step 3 if the tension still needs to be increased.
Decrease the spring hinge's tension by placing the tip of a awl or nail set into an open hole in the adjustment ring at least two positions away from the locking pin and push the adjustment ring horizontally away from the door until the locking pin can be removed and relocated in the adjustment ring hole next to it toward the jamb. Release the pressure to allow the locking pin to rest against the stop.
Open the door and allow it to close. Repeat Step 5 if the tension still needs to be decreased.
Tips and warnings
- Test the door swing periodically during the adjustment of the hinge to prevent overtightening the hinge spring.
- When adjusting double-swing spring hinges or doors equipped with more than one spring hinge, the adjustments must be made to each adjustment ring equally.
