These are the new and improved generation of large folding angles and rulers engineered for multi-use frame-of-reference applications. All edges are dual graduated for left-or-right hand reading from both sides. You can now use the vertical side as a true staff gage with “zero” starting at floor level. A small hole on the folding angle at the top permits hands free hanging with the use of a pin or nail.
Units are constructed of 1/16” thick semi-rigid plastic with the folding angles joined together with 3/16” diameter brass eyelets. Rustproof and water proof! The Black and Yellow bold graphics are flat finish top coated for a true non-glare photographic surface that also adds extra chemical protection. Both the Fractional and Metric angles collapse to approximately 1½ x 15”. Rules are slightly shorter.
