Made from solid anodised aluminium, the extruded shape maintains stability and minimises flex over the length of the ruler. The design has a safety handle offering extremely good protection when cutting. The measurements are metric and easy to read. The ruler also has a full width (48mm) layer of soft but firm rubber providing a non slip base. The cutting edge is 3mm in height providing a safe cutting edge. This, together with the handle design, offers extreme safety when cutting or trimming any project.
