The 5-Star Mega Hub dome connector is an integral component of all Sonostar Mega Domes and Mega Spheres. There are six 5-Star hubs in every dome, and twelve in every sphere. These 5-Star Mega hub Dome Connectors fit either 1″ or 1.5″ Schedule 40 PVC, and they have molded holes for making easy connections.
- Solid core hubs.
- Stainless Steel nuts and bolts are included.
- The hubs themselves are made of high-strength white PVC, with pre-molded holes for bolt fasteners placed 1/2″ from the end of each arm.
- 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.
- The inside diameter of the MegaHub corresponds to the outside diameter of a 1″ piece of PVC pipe
