Claim:
1. A measuring apparatus comprising: a body having a first end, an opposing second end, and a longitudinal reference line extending between the first end and the second end; a first pair of parallel surfaces of equal length, the first pair of opposing parallel surfaces longitudinally between the first end and the second end and parallel to the reference line, the surfaces of the first pair spaced apart by a first distance; a second pair of parallel surfaces of equal length, the second pair of parallel surfaces longitudinally between the first pair of parallel surfaces and the first end, the surfaces of the second pair spaced apart by a second distance that is smaller than the first distance; a surface positioned substantially perpendicular to the reference line and adjoining one surface of said first pair of parallel surfaces and one surface of said second pair of parallel surfaces; and a pair of nonparallel surfaces connected at an obtuse angle, the opposing nonparallel surfaces longitudinally between the second pair of opposing parallel surfaces and the first end.
