The Mayline E-Z Grip Parallel Ruling Straightedge 7250A is made of black phenolic laminate for a drafting bar that is hard and strong despite weighing only a few pounds. Phenolic resin is known for its resistance to heat, shock, stress, and corrosive chemicals. A transparent blade is inserted into the side of this parallel straightedge so you can easily see what you're drawing. The blade is raised above the surface to prevent smudging and smearing. Braking knobs on either side of this Mayline parallel bar allow you to easily lock it in place. You don't have to worry about disrupting your work when you adjust your table or accidentally knocking your mobile parallel straightedge out of place. Whether you are making lettering guidelines or sketching ideas for a computer aided design, a Mayline straightedge won't let you down.
This parallel ruling straightedge has several features designed to make drawing impeccable horizontal and vertical lines as effortless as possible. The E-Z Grip cap is a textured bar that runs the full length of the straightedge. This comfort grip bar is raised by 5/16” to make controlling your straightedge a breeze. It also gives you a handy place to put your tools, especially when your drawing board is set at an angle. Your Mayline parallel bar purchase includes all the necessary hardware for mounting the drafting bar above your drawing board. Stainless steel braided nylon-coated guide wires on either side give durable and balanced stability. Self-lubricating pulleys ensure smooth operation.
This Mayline drawing board straightedge comes without an optional Armoredge stainless steel protective strip. This fine, nearly invisible strip of steel is inserted above the raised inking edge and prevents nicks and dents from your drafting tools. You have a choice of 5 sizes for this Mayline parallel ruling straightedge: 30”, 36”, 42”, 48”, or 60” lengths are available. This measurement is for the full length of the straightedge blade from end to end. The blade measurement is also the minimum size of tabletop drawing board this parallel straightedge will fit. For example, you can install a 36” drafting bar on a 48” table, but it will not fit on a 32” table.
Mayline makes some of the best drafting equipment available. Each Mayline mobile parallel drafting straightedge comes with a limited lifetime warranty.
