The house number is 35 inches long. The aluminum numbers are ½” thick and 5” high. I order the aluminum letters with weld tabs. Welding the number to the 18 gauge sheet metal made it difficult to paint. Because of the lack of paint behind the aluminum numbers, there will eventually be rust stains below the numbers. The next time I will try to attach the numbers by drilling and tapping. The house number is supported at both the head and at the end of the 18 gauge pendant.
