Abstract
A case for an elongated tool such as a level or the like includes outer walls which cooperate to define an internal cavity into which the tool is placed. Spaced indentations are provided along the length of the case, with the indentations extending around the entire periphery of the case. Each indentation provides a supporting surface adapted for placement closely adjacent an outer surface of the tool, for maintaining the tool out of contact with the outer walls of the case. An end cap encloses the open end of the case for securing the level therein, and indentations are formed in the end cap and in the end of the case for spacing the ends of the level inwardly from the end walls. The level is cushioned by an air space between the outer surfaces of the level and the inner surfaces of the outer walls.
