INCRA 4-Pc. Marking Rule Sets

Each set includes the Precision Marking Rule, Precision T-Rule, Precision Bend Rule, and a fine 0.5mm marking pencil. See more measuring & layout tools.

The sets are offered in 6" and 12" versions, each containing the same three rules and marking pencil.

Each 0.5mm guide hole or slot captures your pencil or scribe at the exact scale position, so the mark lands precisely without parallax or angle slip from viewing the scale at an angle.

Micro-fine guide holes and slots are located at every 1/16", 1/32", and 1/64" scale position, and the Professional T-Rules even offer marking holes every 1/100".

With the pencil set in a marking hole, you slide the T-Rule along any edge to draw perfectly placed, repeatable horizontal lines. Browse more marking & layout guides.

The Bend Rule draws perfect horizontal lines using its end marking holes while sliding along the edge of your work, and it makes carrying an accurate mark from one side of a board to the other easy.

Yes. A fine 0.5mm marking pencil is included with each set, sized to fit precisely in the rules' guide holes and slots.

The guide holes and slots are sized for a 0.5mm pencil or a sharp scribe, which is why the 0.5mm pencil is supplied with the set.

INCRA marking rules locate your pencil at the exact measurement with zero uncertainty and no eye strain, which a plain ruler cannot do. Pair them with our rulers & squares for complete layout coverage.

Yes. Because each mark is captured in a fixed guide hole, you get consistent, repeatable lines every time, which is ideal for joinery and project layout.
