Door closer adjustment mechanism

An adjustment indicator mechanism for a door closer including a tubular portion and an adjustment screw mounted to the tubular portion, wherein the adjustment screw is operable to adjust a closing force of the door closer to thereby adjust a size of the door closer, the adjustment indicator mechanism comprising:

• a housing configured for mounting to the door closer, the housing comprising a channel and indicia located adjacent the channel, each of the indicia corresponding to a respective size of the door closer;
• an adjustment transmission mounted in the housing, wherein the adjustment transmission includes a first component configured for coupling with the adjustment screw such that the adjustment transmission is operable to rotate the adjustment screw;
• an indicator transmission engaged with the adjustment transmission and mounted in the housing;
• and
• an indicator movably mounted to the housing such that a portion of the indicator is visible via the channel, wherein the indicator is engaged with the indicator transmission such that movement of the indicator transmission causes the indicator to selectively align with the indicia to thereby indicate the size of the door closer.
