SPRING ADJUSTMENT INDICATOR FOR A DOOR CLOSURE
A spring force indicator for a door closure having a spring force spring force adjuster comprises a drive wheel coupled to the spring force adjuster for rotation therewith and a driven wheel. The driven wheel includes a disc and a post extending from the disc, the post being disposed in a bore formed in a front surface of the door closure and adapted to engage the drive wheel for rotation therewith. The disc further includes first indicia. A cover includes a base wall and a cylindrical sidewall depending from the base wall, the cover being disposed on the end of the door closure and configured to cover the drive wheel and the driven wheel. The cover includes a central aperture for receiving the spring force spring force adjuster, a second aperture disposed between the central aperture and the sidewall, and second indicia disposed around the second aperture. The first indicia is visible through the second aperture, and the first indicia cooperates with the second indicia to indicate a measure of spring force.
