This 6V Mega Dome Hub Kit is designed for use with 1" or 1.5" Schedule 40 PVC tubing. This is the biggest and strongest kit we offer. It uses Sonostar Mega Dome Connectors which add additional strength to the dome. Combine the Basic Hub Kit with the Strut Kit for a quick build, or checkout with just the Basic Hub Kit and use the calculator below, under helpful tools, to determine what size struts you will need to cut for the size dome you are looking to build. If you don't see the size you are looking for click the custom kits button to submit and inquiry.
Because of the extreme angles, we recommend NOT using glue for the 6V Megahub domes. On any dome less than 50’ in diameter, the angles will cause the struts to come out of the hubs before the glue can set. For the same reason, we do not recommend building any 6V Megadome of less than 50' diameter.
|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 (Hub + Strut Kit).
To complete a Hub + Strut Kit order simply choose from several options based on the diameter of the finished dome.
The 6V 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. The frequency 6 (6V) dome is the strongest configuration that we makes, and this dome can easily be built up to 50 feet in diameter without any structural issues. There are nine different sized struts in Frequency 6 domes, and you can find those lengths using the Sonostar calculator. All the MegaHubs are predrilled, so you have the choice to either glue/weld the connections for a more permanent build, or use nuts & bolts, so that you can put the dome up and take it down when you need to.
