Dimensional Measuring and Size Checking

Certified Lightweight Aluminum Rulers

Ensure accurate measurements with these certified rulers.

Lightweight Aluminum Rulers

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

Easy-to-Read High-Contrast Rulers

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

Vertical Rulers

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

Large-Capacity Slide Ruler Calipers

These calipers have deep jaws for measuring large-diameter objects, such as pipes, poles, and logs.

Linear Scales with Digital Readout for Milling Machines

Retrofit your manual milling machine with a digital readout system. It measures and displays precise tool and workpiece positioning on two axes.

Linear Scales with Digital Readout

This digital readout system displays precise positioning on one axis. For use with machines that perform dry machining and cutting applications, such as table saws, band saws, planers, and drill presses.

Linear Scales with Digital Readout and Fence for Saws

Install a digital readout stop and fence system onto the setup for your miter, chop, or radial arm saw. It displays measurements on one axis, allowing you to cut pieces up to 94" with high precision.

Linear Scales with Digital Readout for Lathes

Mount a digital readout system onto your manual lathe. It measures and displays precise tool and workpiece positioning on two axes.

Squares with Graduations on Both Blades

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

Angle Squares

Also known as rafter squares, these have a 0° to 90° scale for measuring angles.

Long-Arm Protractors

Handle big jobs such as sheet metal fabricating and pipe bending with these long-arm protractors.

Digital Protractors with Level and Laser

A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle.

Digital Protractors with Level

These tools have front and back digital displays, as well as horizontal and vertical vials.

Digital Protractors

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

Diameter Identifiers

Measure the outside diameter of small round- and hex-shaped objects such as rods, drill bits, bolts, and tubing with this pocket-size tool.

Layout Marking and Drafting Tools

T-Squares

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

Multi-Angle Transfers

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

Levels with Rulers

Align and measure at the same time with these levels that have rulers on the front and side.
