We got her up and standing tall. 7-1/2 foot, 342 pounds. Made by Sediver out of Brazil. Drilled down 24-inches into this tough Texas ground and back filled with concrete and steel. This monster is anchored to mother earth by four 5/8" x 24" long anchor bolts embedded into the concrete. This is one of the tallest glass columns that Sediver manufactures. They can go taller but you have to stack them like the common porcelain units that are used in today's substations in the U.S.A.
