professional sign installationOur portable signs are blue and white, and their attractiveness helps you to maintain the image of quality that you have worked so hard to establish. These signs are constructed of 3/16" tubed steel, and weigh over 400 pounds! The "MAC" sign is far ahead of any of its competition in attractiveness and durability. The height of the sign exceeds eight feet, helping to overcome competition with shrubs, smaller real estate signs, and even some automobiles that would hinder visibility. Our signs are available in three different sizes – 4'x8', 4'x6' and 3'x5' (different zoning restrictions have size limitations.) The "MAC" sign stands tall above the rest!

While the quality of our signs far exceeds our competitors', our exclusive letters are ten inches in height, which surpasses the industry standard of eight inches. They are made of a durable, polyethylene plastic, and we use our own special formula of paint for maximum clarity and visibility. Please don't hesitate to call if we can be of service.
