The Rhino Ruler 55125 is a durable, waterproof fiberglass folding ruler built for professionals who need precision and reliability in the field. Measuring 1/2" x 6', it features engineer’s scale (10ths/100ths) on one side and feet/inches/16ths on the other for versatile measuring.

Constructed from a polyamide composite reinforced with 30% fiberglass, this ruler resists wear, scratches, and swelling—unlike traditional wood rulers. Its deeply embossed markings stay legible even under harsh jobsite conditions, making it a rugged and dependable tool for engineers, surveyors, and construction crews.
