Alvin Deluxe Parallel Straightedges have Comfort Grip Bar & Floating Roller
These drafting parallel straightedge bars have a convenient aluminum comfort grip to easily move the straightedge across your drawing surface. The brushed aluminum surface resists perspiration stains and corrosion and provides a convenient pencil ledge. The straightedge is made of rigid phenolic construction with a black satin finish & features frictionless operation through the floating action of the nylon rollers mounted under the blade. The Plexiglas edges are elevated to prevent ink smears and steel ball-bearing pulleys provide smooth movement. The Paraliner Delux straightedges include all mounting hardware and installation instructions.
