Alvin Parallel Straight Edge 36In

Alvin Parallel Straight Edge 36In
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.
