Precise scribing and layout – with a 400mm straight edge

A fixed 400mm reference length gives a continuous edge for pencil or scribe contact across typical workpieces. Reviews note the straight side helps achieve repeatable lines without needing multiple transfers.

Clear, straight reference lines speed up cutting and assembly work and reduce layout errors.

Consistent readings under routine use – with alloy-steel construction

Single-piece alloy-steel construction from product information helps the edge retain straightness and resists minor knocks that can alter accuracy. The solid metal composition provides a stable contact surface when checking flatness and alignment.

Reliable measurements reduce the need for repeated checks, saving time on site or in the workshop.

Practical for everyday tasks – with a compact, toolbox-friendly length

At 400mm the straight edge covers most routine marking and layout requirements while remaining small enough to store in a tool bag. The size suits common sheet sizes and small joinery components.

Easy to carry between jobs while still wide enough for many marking and alignment tasks.
