Made from .063 Aluminum, the same guage of non-corrosive metal used by metro systems worldwide and coated with a durable, glossy paint. Underground Signs custom letters each sign to order using the same fonts, proportions, and design standards as the MTA, MBTA, and CTA and finishes them with clear laminate.

Size: 72 x 9 x 1"
