Adjustable trim ring for deadbolt locks

An extendable trim ring for a door lock, comprising:

• a flange abutting a door and including a base defined by an annular protruding lip, said lip being interrupted by a plurality of notches to define a corresponding plurality of protruding spacers of alternately longer and shorter extent;
• and
• a collar slidably and rotatably received within said flange, said collar having an annular wall seated within said flange, and the annular wall being formed with an inner surface defined by a plurality of recesses tracks for slidably receiving the alternately longer and shorter spacers of said flange;
• whereby said collar may be extracted from said flange to withdraw said spacers from said recesses, rotated, and reseated to adjust extension of said collar from said flange.

An extendable trim ring for a lock, comprising:

• an annular flange defined by a tubular wall outwardly-encircled by a protruding lip defined by a notch, a rim of said tubular wall being defined by alternately longer and shorter teeth;
• and
• an annular collar slidably received within said annular flange, said annular collar having a tubular wall seated within the notch of said flange, and the tubular wall having an inner surface defined by a plurality of recessed axial tracks for slidably receiving the alternately longer and shorter teeth of said flange;
• whereby said collar may be pulled from said flange to extract said teeth from said tracks, rotated, and reinserted for pull-and-twist adjustment of an extension of said collar from said flange.
