The 26 ft 2 x 6 and 2 x 4 dome with X1 (green) and FI (Face Intermediate
- brown) subdivision struts. The large triangles on this 2 frequency icosa
dome are nearly 8 x 8 x 10 ft. A door retrofit, riser wall (Vertical Base
Option, cement perimeter wall etc.) and cupola will work well on this dome.
Height is slightly more than radius.
