Alvin Deluxe Paral-Liner Straight Edges

Deluxe version of the popular Paral-Liner Series, with an integral comfort grip bar to control straightedge movement. The brushed aluminum surface resists perspiration stains and corrosion, and provides a convenient pencil ledge as well. The floating roller movement allows the draftsman to move the straightedge with minimal effort and then lock it in place.
