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

Extend the blade to draw circles up to 144” diameter.

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

Mark and transfer distances from the outer edge of an object.

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

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.

Make blunt and sharp points.

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

This ink is waterproof and dries quickly.

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

Remove unwanted pencil marks with ease.

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

Lay out pipe and structural steel for any type or size of pipe fitting—elbows, tees, and wyes of all angles.

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

Trace smooth curves.

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

Form custom shapes for drawing.

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

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

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.

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

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