Self-Opening Reverse-Acting Door Hinge Springs, 4-Piece Set

Four reverse-acting door hinge springs

This set contains four steel coil springs for a compatible door hinge arrangement. Each spring has a central coil and two bent arms, with black-covered sections at the outer ends. The loose springs let you replace the spring component while retaining suitable existing hinge hardware.

The self-opening, reverse-acting designation refers to an opening bias when the spring is correctly fitted. The result depends on the hinge layout, where the two arms bear, and the direction the door swings. Check those details before choosing this set; the opening angle and force are not specified.

Match the hinge and opening direction

Compare the coil opening and arm bends with the hinge you plan to use. There must be room for the coil, suitable contact points for both arms, and clearance through the intended swing. A similar-looking hinge does not establish a match, and this set has no confirmed hinge brand, pin diameter or left/right application list.

Plan the spring installation

Use installation guidance for the specific hinge and spring arrangement. Have the spring direction and fit checked before loading the spring or putting the door into service. Spring count per door, preload and door weight limits are not provided, so the four-piece package should not be treated as a prescribed installation for one door.
