Starrett Small Steel Rules with Holder
1/4, 3/8, 1/2, 3/4, 1″

This set of five small rules is extremely useful
for measurements in confined or hard-to-
reach locations . They are especially suitable
for measuring grooves, short shoulders,
recesses, keyways, and in tool and die work .
The 4″ long holder is well balanced . The rules
are easily inserted in the slotted end of the
holder and are rigidly clamped in place by
a slight turn of a knurled nut . Two slots are
provided, so the rules can be held at 30º or
45º, either square in a slot or tipped to one
side .
Thicknesses up to 1/16″ can be clamped in
either slot . Rules are made of thin, spring-
tempered steel, with bright finish and highly
accurate, photo-engraved
graduations . Each rule is graduated in 32nds
of an inch on one side and 64ths on the
reverse .
