A tribeam is used when you’re building on one tree and two posts, a treehouse between two trees. Or if you have 3 trees you can put a tribeam on one tree and span to the other two trees with beams resting on the tribeam(you would then run you joists perpendicular across the two main beams)

This will support half of a 200-250 square foot treehouse or smaller. Note: if you’re in a heavy snow load area and close to that range we recommend going up to the large TABs tribeam kit.

Also note: when you get to this size special consideration needs to be taken into the size of the lumber used for the tribeam.

Qty 1 - Double Knee Brace
