Abstract
Certain embodiments relate to an adjustment indicator mechanism for a door closer including a tubular portion and an adjustment screw mounted to the tubular portion. A housing is configured for mounting to the door closer, and includes a channel and indicia adjacent the channel, each of the indicia corresponding to a respective size of the door closer. An adjustment transmission includes a first component configured for coupling with the adjustment screw. An indicator transmission is engaged with the adjustment transmission and mounted in the housing. An indicator is movably mounted to the housing such that a portion of the indicator is visible via the channel. 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 current size of the door closer.
