As previously mentioned, having the right tension in your double acting spring hinge is important in order to control the speed at which the door opens and closes. If the spring-loaded hinge has too little tension, the doors will droop or sag; whilst if the doors have too high tension the doors will require a lot of force to be opened, and swing back into position with a lot of force.
To adjust the tension of a double acting spring hinges you will first need to remove the locking pin from each hinge. Next, use a tensioning rod in the tensioning hole to adjust the spring tension. Please note, that after changing the tension on double acting spring hinges it is important to test the doors in both directions to test the force and speed at which they move.
It is also advisable to notify anyone who regularly uses the door of the alterations in order for them to be aware that the doors may require less or more force in order to be opened or closed.
