Turn your ruler into a compass by adding these point-holding clamps.

Combine these point-holding clamps with a pipe to create a compass that marks circles 1 1/2" diameter and larger.

Compasses have spring tension joints that stay rigid to draw large circles up to 100” diameter.

Draw circles up to 24" or add Extension Beams for Expandable Beam Compass to create even larger circles.

Accurately mark and measure.

Draw or scribe circles and transfer measurements.

Unfold and lock the corners to form a triangle for marking angles.

Mark and cut straight lines or 90° angles.

Take measurements off of scaled architectural or engineering drawings with these specialized scales.

Draw and cut straight lines in drafting, graphics, and construction applications.

Hold 2 mm lead for drawing or drafting.

Create precise drawings with these pens.

Erase only what you mean to.

Knead the pad to release a grit-free powder that absorbs dirt and other material from drawings and tools.

Create high quality technical drawings with this vellum paper that is designed to work in laser printers.

Trace smooth curves.

Form custom shapes for drawing.

Trace numbers and letters in three different heights.

Transfer contours, patterns, and shapes for applications such as fitting floor tile and installing pipe insulation.

Transfer multiple angles, draw parallel lines, or create a template to make repeated patterns and measurements.

Locate and mark the centerline on rods, tubes, and pipes, lay out keyways, and establish angles for connections.

Protect your boards with these plastic covers.

Also known as try squares, these are square inside and out for checking and marking angles.

Ensure reliable, repeatable angles.

Also known as carpenters’ and framing squares, these have graduations on both blades for horizontal and vertical measurements.

Lay out machine tables and work stations at precise right angles. This laser generates two red lines that form a 90° angle.

Replace your try square, miter square, depth gauge, height gauge, center-point finder, and level. The blade on these squares meets Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

Use these squares in place of your try square, miter square, depth gauge, height gauge, center-point finder, and level.

Precisely measure angles on molds and jigs.

Set bevels and measure angles. Also known as bevel protractors, these have an adjustable arm.

Take precise measurements with this protractor.

Measure angles and dimensions with one tool.

Use these protractors to measure angles and dimensions.

These magnetic tools have one digital display and a lock to hold the arms in position.

Attach to curved or flat steel surfaces.

Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Permanently mount these vertical rulers to walls and tanks.

Fold these rulers for convenient storage and transport.

These rulers include a certificate of calibration traceable to NIST with test measurements that confirm accuracy.

High-powered magnets hold these rulers in place.

Made of wood with a clear protective coating, this ruler is an economical choice for measuring objects up to three feet long.

Permanently mount these rulers to a machine or workbench.

Made to last, our most corrosion-resistant rulers are stainless steel and have wear-resistant etched markings.

Made of aluminum, these rulers are an economical alternative to stainless steel rulers.

Ensure accurate measurements with these certified rulers.

Rulers have large numbers and deeply etched graduations.

Numbers and graduations etched in light colors are easy to see on a black background.

A clear protective coating and brass endcaps add durability to these hard-maple rulers.

Measurements are printed from top to bottom for measuring heights and depths.

Permanently mount these rulers on machines, tanks, and walls to measure heights and depths.

A hook grabs the edge of an object for easy alignment.

Line up two pipe flanges and determine pipe angle with the included nut-and bolt pins, level, and protractor.

Each step on these aligner pins matches common bolt holes on pipe flanges, so they're more precise than conical aligner pins and don’t require nuts. Press the pair of pins into mated flanges to make sure the flanges are aligned.
