Made using 7075-T6, 3/8 material (9.5 thick) These towers have been hard bashed by out test team and taken some seriously bad crashes with no ill effect. The square frame approach should add very good support all around the tower and the (stubby ear design) should make it very rigid. We have also added material in center where the part normally bends and added a tapered cut to provide more support at the bottom screw area. THEY HAVE A POLISHED FINISH.
