Abstract

A unique triangular point for use by a glazier has a star shaped central opening such that a plurality of such points can be stacked in oriented relationship to one another, and can be retained by a cotter key having skewed legs such that the key is easily inserted in opposed notches of the aligned openings in the points, and such that the key can be twisted for removal when inserting the stack of points in a conventional point driver. A plastic retainer is also disclosed and is adapted to fit into the aligned openings of the stacked points.
