INCRA Protractor - Manual

Easy and Accurate
To mark with a 0.5mm Mechanical Pencil: Just hold the pencil vertically and draw a short line in one of the slots,
or twist the pencil in a hole to mark a dot.
To mark with a Wooden Pencil:
First, sharpen the pencil, then twist the lead once or twice in any one of the holes to
give it an ultra fine point ready for marking.
To mark with a Metal Scribe or Center Punch:
Any scribe or center punch sharp enough to fit through the holes can
be used. Use finger pressure ONLY to mark a precisely located “dimple” in soft materials such as wood, paper, plastic,
brass or aluminum. DO NOT damage your precision rule by pounding the point through the hole with a hammer.

Precision Protractor
Your INCRA Protractor is a precision measuring and marking instrument for use in many applications.
Strike a
perpendicular
line across your
workpiece at the
desired vertex.
Align protractor
with vertex line:
Put the T‑Bar against
the edge of your workpiece
and position the
protractor so the vertex
line is visible through the
90° window.
Mark your angle:
Draw a short line in one
of the slots, or twist the
pencil in a hole to locate
your mark at the desired
angle.
Locate the vertex on
your drawing:
Draw two perpendicular
lines that intersect at the
desired vertex.
Position
protractor and mark
your angle:
Use the windows feature
to align the protractor
with the vertex on your
drawing. Place a mark at
the desired angle.
Adjusting the T-Bar:
If you loosen or remove
the thumbscrews, be sure
to place the ruler edge
of the protractor firmly
against the indexing
lip on the T‑Bar before
retightening to insure
perfect accuracy.
INCRA has re-invented the protractor by putting
micro-fine marking holes at every half degree angle
to locate a sharp pencil point or scribe exactly on
target! Now, instead of squinting as you try to
line up your pencil on that blur of lines along the
edge of your old protractor, you can instantly put
your mark precisely where you want it with zero
uncertainty and no eye strain.
When accuracy counts … INCRA RULES!
INCRA RULES are available in many other popular styles and lengths.
