|1) CHOOSE KIT||2) CHECKOUT|
Choose whether you would like to order just the Basic Hub Kit and cut the struts yourself, or order the Basic Hub Kit together with a set of precut, predrilled, color-coded struts (Full Kit).
To complete a Full Kit order simply click the ADD STRUTS button to choose from several options based on the diameter of the finished dome.
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.
