The apparatus may include a housing that is sized for placement in an opening in the door and an adjustment member that is structured for at least selective axial displacement about the housing. At least a portion of the adjustment member may be structured for placement adjacent to an outside portion of the door. The apparatus may include an indicator assembly having an indicator gauge that is biased against the adjustment member by a biasing element. The indicator portion is structured for axial displacement about the housing via the axial displacement of the adjustment member. The indicator assembly may also include a cover having an opening that provides a visual access point for an indicium of the indicator gauge. ## Claims ### Claim 1 An apparatus comprising: an outside housing, at least a portion of the outside housing structured for placement within an opening in a door;

and an indicator assembly having an indicator gauge and a biasing element, the indicator gauge having a plurality of indicium corresponding to a thickness of the door, at least a portion of the indicator gauge structured for axial displacement along one or more channels of the outside housing, the indicator gauge being axially displaced by the axial displacement of the adjustment plate, the biasing element structured to bias the indicator gauge against the adjustment plate. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the outside housing includes a slot, the slot structured to receive placement of at least a portion of a slide assembly of a lock assembly. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the adjustment plate is axially displaced about the outside housing via rotational displacement of at least an internal thread of the adjustment plate about an external thread of the outside housing. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the outside housing comprises a hub portion and an arm portion, the external thread being positioned about at least a portion of the hub portion, and wherein the one or more channels extend along at least portions of the hub portion and the arm portion. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the indicator gauge includes an indicator portion and a leg portion, the indicator portion including the plurality of indicium, the leg portion having an extension that is structured to extend from the one or more channels to contact at least a portion of the adjustment plate. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the indicator assembly further includes a cover, at least a portion of the cover structured to cover at least a portion of the one or more channels, the cover including an opening positioned for visual access of one of the plurality of indicium. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the cover has a first portion and a second portion, the first portion extending along a first longitudinal axis, the second portion extending along a second longitudinal axis, the second longitudinal axis being non-parallel to the first longitudinal axis, the first portion including the opening, the second portion structured to abut against a face portion of the arm portion. ### Claim 8 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. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the adjustment member is axially displaced about the housing via rotational displacement of at least an internal thread of the adjustment member about an external thread of the housing. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the indicator assembly further includes a cover, at least a portion of the cover structured to cover at least a portion of the indicator portion, the cover including an opening positioned to facilitate visual access of one of the plurality of indicium. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the cover has a first portion and a second portion, the first portion extending along a first longitudinal axis, the second portion extending along a second longitudinal axis, the second longitudinal axis being non-parallel to the first longitudinal axis, the first portion including the opening of the cover, the second portion structured to abut against a face portion of the arm portion. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein housing includes a groove adjacent to a face portion of the housing, the groove sized to receive placement of the second portion of the cover. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the leg portion has a non-circular cross sectional shape that is dissimilar to a corresponding cross section shape of the indicator portion. ### Claim 14 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. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the indicator assembly includes a cover, at least a portion of the cover structured to cover at least a portion of the first channel, the cover having an opening sized to provide visual access to one of the plurality of indicium of the indicator portion. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein an end of the indicator portion includes an aperture sized to receive insertion of at least a portion of the biasing element. ### Claim 17 (depends on 16) The apparatus of claim 16, wherein the hub portion includes an inner aperture, and wherein the at least one arm portion includes at least opposing first and second arm portions, the first and second arm portions spaced apart to provide a slot that is sized to receive placement of at least a portion of a slide and a slide clip. ### Claim 18 (depends on 17) The apparatus of claim 17, wherein the cover has a first portion and a second portion, the first portion extending along a first longitudinal axis, the second portion extending along a second longitudinal axis, the second longitudinal axis being non-parallel to the first longitudinal axis, the first portion including the opening of the cover, the second portion structured to abut against a face portion of the arm portion. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein an end of the cover includes a recess sized to receive slideable insertion of at least a portion of the leg portion of the indicator gauge. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the leg portion has a non-circular cross sectional shape that is dissimilar to a corresponding cross section shape of the indicator portion.
