Sonostar's 2V megahub + Strut using 1" PVC strut kit is more than twice as strong as the 2V standard dome. The megahubs are more robust, and the 1" PVC is thicker, adding strength to the whole structure. With this kit, you have everything you need to build a solid 2V frame. This is the least complex configuration, consisting of only 65 struts and 26 hubs and all the nuts and bolts needed to fasten it together. It is a tried and true solution to enclosing space with a freestanding frame and no internal support poles.
