ABSTRACT:
Metal board holder used in the construction industry having base and body plate members. Each member has a board receiving U-shaped bracket with nail receiving holes. A base plate adjustment slot can receive one or more threaded body plate member extensions which ride in it to permit plate member adjustments with respect to each other. The body plate member is pivotally mounted to its bracket and has several hinged plate sections the lowermost of which mounts the threaded extension. Locking nuts engage the threaded extension when it is inserted into the base plate's slot to fix the plate with respect to each other. Many types of board holding orientations are disclosed.
