Spring adjustment indicator for a door closure
A spring force indicator for a door closure having a 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. A 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 sidewall, a central aperture for receiving the spring force adjuster, a second aperture disposed between the central aperture and the sidewall, and second indicia disposed around the second aperture. The disc includes first indicia visible through the second aperture which cooperates with the second indicia to indicate a measure of spring force.
