Rhino Ruler Waterproof Fiberglass Folding Ruler
The waterproof fiberglass construction prevents common problems that occur with wood rulers such as fading, splintering, and chipping. It outlasts wood rulers four-to-one. Engraved graduations resist weather and scratches. Easy-to-fold locking joints are tighter than traditional folding rulers made of wood. This allows more accurate measurement along the length of the ruler.
