Mobile Parallel Straightedge is constructed from rigid phenolic plastic, finished in black satin. This is the perfect tool for professional engineering and construction applications as well as students. The friction less nylon ‘floating’ rollers on the bottom of the bar retract when the bar is pressed, and, combined with raised clear acrylic edges, help keep the bar off the paper when in motion and thus prevent smearing.
