The Cork Display Rail, also called an art rail or map rail, the cork rail was introduced in the 1940s and was well established in the educational setting by the 1960s. Today it can be found in K-12 classrooms everywhere as designers and architects continue to specify cork rails for new school construction. Cork display rails have survived in the classroom for over a half-century because of their sheer simplicity and unmatched versatility, the same reasons why they're so difficult to replace. So any new display technology that isn't as simple or versatile as cork rail doesn't stand a chance in today's classrooms. And to finally end cork rail's reign, it would also have to excel in areas where cork rails fail!
