Mayline Parallel Rule No Rollers Ez Grip 42in 7252A

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, we designed a straightedge with retractile, ball-bearing rollers of metal or Delrin(plastic) 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 with Delrin rollers for use with drafting films. Above-board mounting hardware included. EZ Grip has a raised middle bar that makes moving the straightedge easier.
