Abstract: A drapery installation tool includes a top and bottom square block held together by a pair of bolts, each block having a groove for adjustably mounting a pair of measuring rules, openings for mounting a pair of spring biased pins, and additional openings forming guides for a drill. The measuring rules locate the pins relative to a window casing. The pins when hit by a hammer form starting holes for drapery and curtain rod brackets in wallboard, or in the alternative, act as center punches in wood and wood panelling. The drill guides are used to guide a drill when starter holes are needed in wood and wood panelling.
