Our 4-Star Mega Hub Dome Connector is used as a base connector for all Sonostar Mega Domes, where the base is at ground level. ‘Mega’ refers to the size of the hubs and differentiates them from ‘standard’ hubs, which fit 1″ or 1.5″ PVC. These are the same connectors that come in Sonostar Mega Dome and Mega Sphere kits. Typically, they are used at the base of a dome, but they can also be used in a doorway, where you remove struts for an opening and you want it to be flush, without the 6-way arms sticking out. Designed to fit either 1″ or 1.5″ Schedule 40 PVC.
- Sonostar 4-Star Dome Connector Hubs are designed to be used with either 1″ or 1.5″ Schedule 40 PVC tubing.
- The inside diameter of the Mega Hub geodesic dome connector corresponds to the outside diameter of a 1″ piece of PVC pipe.
- There is a 12-degree curvature molded into each arm from the hub center, which gives the hubs an ‘inside’ and an ‘outside’ when putting the dome together.
- Stainless Steel nuts and bolts are included.
- Solid core hubs.
