Alvin Parallel Straightedges

Alvin Paral-Liner Mobile Parallel Straightedge

Paral-Liner straightedges have a rigid phenolic construction with a black satin finish. Mobile straightedge affords frictionless operation through the floating action of the nylon rollers mounted on the blade. The rollers retract at a touch, securing the blade for accurate drawing.

Plexiglas edges are elevated to prevent ink smears.  Steel ball-bearing pulleys provide smooth movement. The Paral-Liner comes with all mounting hardware and installation instructions.

Alvin Paral-Liner Deluxe Mobile Parallel Straightedge

This is the 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.

The Guide-Line straightedge is an affordable acrylic straightedge that features an elevated ruling edge for smudge-free inking. Smooth operation is provided by self-lubricating pulleys.

The dual-function tunnel cap serves as a finger grip and cable channel.
