Engineer's Folding Rulers - by Rhino Ruler®



  • Waterproof fiberglass construction prevents common problems that occur with wood rulers such as fading splintering and chipping weather and scratches.
  • Easy-to-fold locking joints are tighter than traditional folding rulers made of wood
    allowing for a more accurate measurement along the ruler’s length.
  • Engraved graduations resist weather and scratches.
