ABSTRACT:
A chalk line end is disclosed which includes a substantially flat base member having first and second tabs depending therefrom in order to form a substantially 90 degree angle to the base member. First and second points extend from the respective first and second tabs and are sized and shaped so as to press into the side surface of a board when the chalk line end is positioned over the board edge. This arrangement facilitates maintaining the position of the chalk line end as the chalk line is drawn off at an angle to the board edge. As an optional feature, a chalk line mount may be coupled to the base member by means of a swiveling connector, such as a rivet. This swiveling connection facilitates drawing the chalk line off at an angle from the board edge.
