ABSTRACT:
A first insert is arranged to be engaged with one surface of a matchboard in alignment with a bore in the matchboard. A second insert has a portion thereof arranged to be engaged with the opposite surface of the matchboard at the bore. The first and second inserts have impression forming portions arranged to make recess and projecting contours respectively in impression material with a close tolerance interfitting engagement when in facing relation to provide anti-shifting connection to opposed portions of the impression material. The inserts have a telescoping engagement which precisely aligns the first and second inserts in their impression forming functions, and such telescoping arrangement provides adjustable mounting of the inserts on matchboards of different thicknesses.
