Mayline Parallel Ruling Straightedges

Mayline Mobile Parallel Ruling Straightedges

Perfect for engineering and construction applications. Every Mayline parallel ruling straightedge begins with a durable, black phenolic laminate base where we inset a transparent blade for see-through registration and fine line quality.

For those who work with a variety of surfaces, there is a straightedge with retractile, ball-bearing rollers of metal or Delrin built right into its base. They literally float over any surface whether it’s paper or film.

The rollers come in chrome-plated brass or plastic. We recommend the plastic rollers for use with drafting films. Above-board mounting hardware is included.

Mayline Mobile Parallel Ruling Straightedges with Armoredge

These models have the same features as all of our other Mayline straightedges.

The Armoredge is a nearly invisible protective strip of 8 mil stainless steel that is applied to the leading edge of the Mayline straightedge to resists nicks and dents from drawing tools.
