Established in 1939 as the Engineering Supply Company, Mayline has come a long way from its expertise in DRAFTING TABLES, BLUEPRINT FILES and STRAIGHTEDGES. The war years capitalized on our high quality and precision manufacturing for providing highly accurate navigational and mapping accessories for all branches of the military. Though still a market leader in manual drawing (we invented the straightedge) and large format filing, Mayline has moved to the forefront of office ergonomics. We offer the market's largest and most diverse selection of MANUAL-ASSIST, COUNTERBALANCE and ELECTRIC SIT-TO-STAND WORKSTATIONS found anywhere.
