Self-adjusting door thickness indicator

An apparatus for setting a lock assembly to accommodate a thickness of a door, the apparatus comprising:

• a housing, at least a portion of the housing sized for placement in an opening in the door;
• an adjustment member structured for at least selective axial displacement about the housing, at least a portion of the adjustment member structured for placement adjacent to an outside portion of the door;
• and
• an indicator assembly having an indicator gauge and a biasing element, the indicator gauge having an indicator portion and a leg portion, the indicator portion having a plurality of indicium corresponding to a thickness of the door, the indicator portion structured for axial displacement about the housing via the axial displacement of the adjustment member, the biasing element structured to bias at least a portion of the leg portion against the adjustment member.

An apparatus comprising:

• an outside housing sized for insertion in an opening in a door, the outside housing having a hub portion and at least one arm portion, the at least one arm portion having a first channel, the hub portion having a second channel;
• an adjustment plate having a flange portion and an annular portion, the adjustment plate structured to threadingly engage the hub portion, the flange portion structured for placement adjacent to an outer surface of the door;
• and
• an indicator assembly having an indicator gauge and a biasing element, the indicator gauge having an indicator portion and a leg portion, the indicator portion having a plurality of indicium corresponding to a thickness of the door, the indicator portion sized for slideable displacement within the first channel, the leg portion extending from the indictor portion and sized for slideable displacement within the second channel, the leg portion including an extension structured to extend above the second channel, the biasing element adapted for placement in the first channel, the biasing element structured to exert a biasing force to press at least the extension of the leg portion against a portion of the annular portion of the adjustment plate.
