4V Mega Dome Kits

The 4V dome is exactly half of a sphere. As the frequency goes up (2V, 3V, 4V, etc.), the 'roundness' of the dome increases, as does its overall strength. There are six different sized struts in Frequency 4 domes, and you can find those lengths using our Geodesic Dome Calculator. We've seen our kits built into event domes, silo domes, PVC chicken coop domes, greenhouse domes, gazebos and more.

All of our MegaHubs have the holes molded into the parts, so you have the choice to either glue/weld the connections for a more permanent structure, or use nuts & bolts, so that you can assemble and disassemble the dome.
