The British made 1000mm/39" straightedge rule is reversible, with metric graduations on one side and imperial on the other. The rule is also equipped with two of the innovative ViperBite™ grips, with one at each end.
When engaged, ViperBite™ will prevent accidental slippage during marking or scoring suitable sheet materials (drywall, sheetrock, insulation board, plywood, rubber, carpet, plastics etc). This increases safety when cutting as a supporting hand is not always needed to press the rule down when scoring.
For regular use there is a laser cut and formed large aluminium handle that enables easy manoeuvrability.
