Octa Dome 4 Class 2 HZ
Unique octahedral symmetry with 2 opposite upper square areas, a large hexagon on top ideal for placing a cupola, and a flat hemisphere ground perimeter with 12 sides. Add a Vertical Base Option or riser wall for increased height and door retrofit. Add the X1 feature for larger domes that need more support structure in the triangles.
A great simple dome with only 31 Connector Hubs! Ideal for sizes around 13 to 30 feet.
The picture album shows the 26 ft dome, with X1 option, doors, cupola, mounting blocks (anchor posts). This is an ideal size for using 4′ x 8′ sheets to cover the dome. About 48 sheets are needed to make the cover triangles.
