A tribeam lets you attach a wide platform to a single tree trunk by
widening the support base on the tree instead of attaching one beam to
either side. It is an inverted truss, with a flat beam on top and two 45
degree braces all locked together with notches and hardware.
This was built by Tree Top Builder's carpenter Paul Gifford during our fall workshop right here in Pennsylvania.
