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

Clamp these point-holding clamps, also known as trammels, onto a beam to create a compass.

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.

A wing joint opens wide for marking and transferring large circles, arcs, and measurements.

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

Probes take the shape of a pipe joint so you can transfer the exact outline to the pipe before you cut.

These 2 mm leads come in a variety of grades, from soft to hard, to meet your drawing or drafting needs.

A protractor and triangle in one, use these tools to quickly set any angle from 0° to 90°.

Mark and cut straight lines or 90° angles.

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

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

Use this vellum paper to produce professional drawings and tracings with lead or ink.

A rule, compass, protractor, and template all in one tool.

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.

Trace shapes such as circles, polygons, arrows, and ellipses.

Trace specialty symbols for pipe fitting, electrical work, plumbing, and more.

Trace smooth curves.

These boards have a mounted sliding parallel rule and a handle for portability.

Illuminate your drafting work and view transparencies, slides, and X-rays.

Measure outer diameter and mark lines around pipe.

Insert a pair of these nut-and bolt pins into adjacent flange holes and tighten to align flanges before connecting two pipes.

Ensure horizontal alignment of pipe flanges with a level rod that runs between two alignment pins.
