Geodesic Hub Connectors

Sonostar hardcore geohubs are the solution to the tedious task of crafting connectors to build geodesic domes. By using these hubs, you will reduce the time it takes to build a dome from days to just a few hours. The hubs themselves are made of tough, durable polyvinyl chloride (PVC), and they are solid in the centers, adding strength and functionality. When you go to cover your dome, you can attach it directly to the hubs themselves by screwing into them, without compromising the strength of the hub. They are engineered specifically for building geodesic domes - designed with a 10 degree curvature to naturally shape the dome as you build it. If you've decided to build a geodesic dome using PVC (schedule 40 or better) poles, then go with the leader in geodesic connectors: Sonostar hardcore geohubs.

We can ship to anywhere in the world. When you get to the checkout, just specify which carrier you want to use.  For International, USPS is usually the least expensive, but it can take longer than FedEx or UPS. 

For hubs that fit 1" or 1 1/2", go to Megahubs from the category menu page.
