ABSTRACT:
A device for installing an article on a vertical surface is disclosed. The device includes a base and a first longitudinal member connected to the base. A second longitudinal member is slidable longitudinally relative the first member. The second longitudinal member is in a telescopic relationship with the first longitudinal member enabling the distal end of the second longitudinal member to be varied in vertical height relative to the base. A template frame is secured to the second member and a plurality of punches are disposed in the frame. The device also includes a lock for locking the relative position between the first and the second longitudinal members, enabling an operator to position the template frame a predetermined distance vertically above the base with the template frame being located in contact with the vertical surface to form an aperture in the vertical surface upon depression of at least one of the plurality of punches to install the article on the vertical surface thereby. In a further embodiment of the present invention a retractable measuring device is connected to the first longitudinal member for measuring laterally relative to the first longitudinal member.
