Industry Leading Durability Our Cast Iron Sign Bases help you display your signs. Ideal for our 12 x 18 inches sign, this Cast iron sign stand comes with a post that inserts into the center of the base, and features predrilled holes for mounting signs. Two pieces of the post easily snap together which then attaches to the base. Unlike any other U Channel Sign Post, our handy Cast Iron Sign Base tolerates winds up to 30 miles per hour. Thick enamel coating on the base and post prevents chips and damage from weather. USA’s Oldest Sign Manufacturer Family owned since 1918, we take immense pride in our signage. Being one of the oldest certainly means we know this business in and out. Our South Dakota factory is the oldest manufacturer of metal signs and hardware in the USA. We have been an integral part of safety and convenience our signs and hardware have provided over the years. Don’t Scrimp on Quality We do not compromise with the quality of our sign hardware and suggest even you shouldn’t. Hardware from competitors has a limited life when exposed to the sun, moisture, and rain in the US. Our baked enameled cast iron ensures years of durability required for outdoor use.
