Product description

The Maun Aluminium Safety Straight Edge 1250 mm (1710-125) is made for work that goes beyond a metre. Its long, lightweight profile gives you one continuous guide across wider material: fewer alignment points, and a protected position for your steadying hand.

Why the Maun Aluminium Safety Straight Edge 1250 mm (1710-125) works

Accurate work. Less rework.

0.105 mmover the full 1250 mm

Over 1250 mm, the bevelled working edge stays within about a tenth of a millimetre (0.105 mm) of true.
It takes accurate cutting past the metre mark without a second alignment point.

Protect your fingers. Control the cut.

1250 mmof recessed finger protection

The recessed profile protects your steadying hand along the full 1250 mm, and the foam-rubber backing helps stop the guide drifting on wide vinyl, film and glass.

Easy to position. Built to last.

40 × 10.5 mmsilver-anodised aluminium

Silver-anodised extruded aluminium takes the effort out of handling a guide this long, and resists corrosion in the workshop and on site.

Best suited to

Manufacturing & Engineering

Choose the Maun Aluminium Safety Straight Edge 1250 mm (1710-125) for wide sheets and panels that extend beyond a metre.

The lightweight aluminium profile takes the effort out of handling, and the accurate bevel, recessed hand channel and non-slip backing support exact layout and safer cutting, with fewer resets.

Model Making & Craft

Use it for oversized model bases, scenery, display boards and suitable sheet materials.

The 1250 mm edge gives you one uninterrupted guide across work that would force a shorter tool to be realigned.

Sign Making

Ideal for wide vinyl, printed film, laminate and sign faces.

The continuous bevel helps prevent stepped trim lines, and the foam-rubber backing grips smooth graphics during the cut.

Interiors & Flooring

Use this size across wide wallpaper, vinyl flooring, laminate, veneer and decorative panels.

The extra reach suits larger installation pieces, and the protected hand position keeps you in control.

Glass Work

Choose it for scoring panes wider than one metre in a single pass.

The non-slip backing steadies the edge on glass, and the recess keeps your fingers away from the scoring tool.

Leatherwork

The 1250 mm guide suits larger hides, long straps and broad leather panels.

It cuts out mid-cut realignment, keeps the knife line visible and helps hold the guide securely on the material.

Frequently Asked Questions

What is a 1250 mm safety straight edge used for?

A 1250 mm safety straight edge is for cutting and scoring past a metre: wide sheets and panels, wide vinyl and printed film, sign faces, wallpaper, flooring, glass panes wider than a metre, and larger hides.

Will a 1250 mm straight edge cover an 8 × 4 ft board?

Across its width, yes. An 8 × 4 board is 1220 mm wide, so the 1250 mm spans it in one pass with a little to spare. It also matches the 1250 mm width of a 2500 × 1250 mm sheet.

How accurate is the 1250 mm safety straight edge?

The bevelled working edge is accurate to 0.001 inch per foot (0.084 mm per metre): within 0.105 mm, or about a tenth of a millimetre, over the full 1250 mm.

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).
