Frequently Asked Questions

What is a 1500 mm steel straight edge used for?

A 1500 mm steel straight edge is used on large sheets, fabricated panels, frames, machine-installation work and long gasket material. Leatherworkers use it for large hides, full-length straps and long panels.

Will a 1500 mm straight edge cover a 3000 × 1500 mm sheet?

Across its width, yes: it spans the full 1500 mm. For the long side, the Maun Aluminium Safety Straight Edge comes in 2000 and 3000 mm lengths.

Should I choose steel or aluminium at 1500 mm?

Choose steel for scribing, gasket work and heavy knife work, where reassuring weight and a hard-wearing bevelled edge count. Choose the 1500 mm aluminium safety straight edge where finger protection, non-slip grip and lower weight matter more. Both are accurate to 0.001 inch per foot (0.084 mm per metre).

Size check: is 1500 mm 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).
