STARRETT NO. 439 SERIES BUILDERS' COMBINATION TOOL - 24"

Combines 7 useful functions in a single, compact, and practical unit that is invaluable for carpenters, builders, pattern makers, cabinetmakers, and machinists. It acts as a ruler, square, level, plumb, protractor, bevel, and pitch-to-foot indicator.

The device includes a 9" long stock, a hardened, machine-divided 1-1/2" wide x 24" long blade, and a protractor. The blade has 4 graduated scales (8ths, 16ths, 32nds, and 64ths).

One side of the protractor is graduated from zero to 90 degrees in both directions to show both the direct and supplementary angles. The opposite side is graduated in 1/2" pitch increments from 0-12" per foot pitch.

The stock includes four levels. This permits leveling or plumbing work in any angle or pitch. USA
