The Draper D19 Aluminium Rule in the 39″ / 1m size is the longest option in the range, making it ideal for larger-scale measuring tasks on construction sites, workshops and fabrication environments. This extended length allows you to measure substantial workpieces, timber lengths and building materials in a single pass without repositioning. Extruded from 30mm wide anodised aluminium, this metre-long rule provides excellent rigidity across its full length, preventing the flex and bending that can compromise accuracy with longer measuring tools. The clear graduations on both sides display metric measurements in millimetres and centimetres alongside imperial measurements in inches and 1/8″ increments, whilst handy conversion tables provide quick reference for length, area, volume and weight equivalents between measurement systems. Features and Benefits: • 1m/39″ length perfect for larger measuring applications • Clearly graduated both sides with cm/mm and 1/8″/inches scales • Handy metric/imperial conversion tables included • Extruded from anodised aluminium 30mm wide for maximum rigidity Contents: • 1 x Aluminium Rule, 1m/39″
