Fibreglass Metric Folding Rule

Made in strong white high-visibility glass fibre, this unique folding rule has a patented hinge design so that when only half opened the rule may be formed into a simple square for basic marking out. The rule, which extends to 2m and folds up neatly for storage, is clearly marked in millimetres with red markings every 50mm for ease of reading. Available with metric graduations only, scaled both sides reading left to right or vice versa.
