Structure mountable assembly

摘要

A modular tool assembly including a tool base configured to releasably secure a modular tool arrangement in a fixed relationship relative to a mounting surface. The tool base includes an upper housing portion and a lower housing portion having a mounting seal extending therefrom. The mounting seal cooperates with the mounting surface to define a vacuum pocket therebetween. A vacuum generating mechanism is configured to remove air from the vacuum pocket through an aperture in the lower housing portion. A modular tool attachment releasably engages a portion of the tool base to secure the modular tool attachment to the tool base. The modular tool attachment can include a self leveling laser leveling device having a laser light source mounted within a housing to project an alignment beam through an opening in the housing to denote a reference plane along the mounting surface.
