Abstract:
An improved added measurement system for use on at least one surface of a substantially rectangular piece of construction material so as to provide a visually precise means for fast and accurate cutting and installing of construction materials whereby use thereof will reduce construction costs by minimizing the amount of labor required to measure construction materials, secure said construction materials in place, as well as minimize material waste due to inaccurate cutting of the piece of construction material, said improved gridded measurement system comprising a plurality of visually precise horizontal unit measurement markings and a plurality of visually precise perimeter vertical unit measurement markings, a plurality of successively higher visually precise numbers associated with said horizontal unit measurements markings and said vertical unit measurements markings, a plurality of visually precise grid markings substantially filling the central portion of the construction material, said system also comprising marking means for visually precise marking of said unit measurement markings, said grid markings, and said successively higher numbers onto the construction material surface, said system further comprising two each of said horizontal unit measurement markings and said vertical unit measurement markings being positioned around the perimeter of the piece of construction material and the remainder of said horizontal unit measurement markings and said vertical unit measurement markings being positioned uniformly throughout the central portion of the piece of construction material to form non-perimeter horizontal and vertical unit measurement markings, wherein the improvements comprise a plurality of visually precise inverted numerals, each of said inverted numerals being identical to one of said numerals and placed in a position close thereto and each of said grid markings also having a spaced apart horizontal distance from the next adjacent one of said grid markings which is identical to the dimension of said horizontal unit measurement markings and a spaced apart vertical distance from the next adjacent one of said grid markings which is identical to the dimension of said vertical unit measurement markings.
