Product description

The 72″ model is the longest Maun steel straight edge. It gives fabricators, installers and leatherworkers a continuous six-foot reference, where shorter tools would mean unnecessary resets.

Across six feet, the bevelled working edge stays within 0.006 inch (0.15 mm) of true.

Best suited to

Manufacturing & Engineering

Choose the Maun Steel Straight Edge Imperial 72″ (1701-072) for six-foot sheets, long fabricated frames, machine beds and installation work.

Maximum Imperial reach means no repeated set-ups.
The rigid carbon-steel body gives you a stable base, the bevel keeps the working line visible, and the 0.001-inch-per-foot accuracy supports practical checks for bow and misalignment.
For inspection-grade flatness, you’ll still need proper metrology equipment.

Leatherwork

The Maun Steel Straight Edge Imperial 72″ (1701-072) is the Imperial choice for full hides, the longest straps and oversized leather panels that need one uninterrupted reference.

Its weight keeps the material under control.
The durable bevel resists repeated knife wear, and with no shorter guide to move, there’s no risk of a stepped or angled cut.

Frequently Asked Questions

What is a 72-inch steel straight edge used for?

A 72-inch (1829 mm) steel straight edge is the longest in the Maun Imperial range. Use it for six-foot sheets, long fabricated frames, machine beds and installation work, and for full hides, the longest straps and oversized leather panels.

What is the longest Maun steel straight edge?

The 72″ is the longest Maun steel straight edge, at 1829 mm. The longest metric steel version is 1750 mm. For anything longer, the Maun Aluminium Safety Straight Edge comes in 1850, 2000 and 3000 mm lengths.

Can I check a machine bed with a 72-inch straight edge?

For practical checks during installation and maintenance, yes. The bevelled working edge is within 0.006 inch (0.15 mm) of true over six feet, and a light behind it shows any visible gap. For machine-tool inspection or recorded flatness results, use a calibrated DIN 874 straight edge.

Size check: is 72″ long enough?

It’s long enough for the width of an 8 × 4 ft board (1220 mm) in one pass.
It’s too short for the length of an 8 × 4 ft board (2440 mm). For that, choose the Maun Aluminium Safety Straight Edge 3000 mm (1710-300).
One size down is the Maun Steel Straight Edge Metric 1750 mm (1700-175).
