INCRA Centering Rule User Manual

12" Precision Centering Rule

Put YOUR Mark on Precision

Any rule can just
measure, but only
INCRA guarantees
YOUR mark of
precision on
everything you do!

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.

Center Finding

To find and mark your center:

Position the centering rule so that it shows
the same measurement at each edge of
your workpiece. Place your pencil in the
zero hole and twist the pencil to leave
your center perfectly marked.

You’ll also find your centering rule handy
for laying out a series of measurements on
either side of any known starting point.
Simply scribe a line at your starting point,
align the zero with your mark, then twist
your pencil through the hole at each of the
desired measurements.

Protractor Feature

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.
