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. Comes with all mounting hardware and installation instructions.
