Abstract
A layout tool is provided with markings (508) and an anchor post (502) for anchoring a layout line, such as a chalk line, in relation to a piece of construction material. The tool (500) includes a chalk line guide assembly (510) comprising a mounting plate (514) which carries a chalk line guide post (512) and a securing mechanism (516) for securing the chalk line guide post (512) and plate (514) at a desired position along an arcuated groove (506) formed in the surface (504). A worker can secure the tool (500) to a work piece and attach a layout line to the anchor post (502). Thereafter, the worker can disengage the securing mechanism (516) to allow movement of the chalk line guide post (512) and plate (514) to a desired position in the slot (506) corresponding to a desired angular orientation of the layout line.
