Q: What’s the most reliable method for attaching a treehouse to a tree?
A: Consider using a Treehouse Attachment Bolt, also called a TAB. This is a specialized piece of hardware designed to carry large loads in a tree while minimizing damage to its cambium. The TAB consists of a tiered bolt with different sized parts, featuring a thick collar or “boss” near the midpoint. The TAB’s threaded end inserts into the tree fully, and the collar inserts halfway. The unthreaded stem section protrudes from the tree and holds the treehouse support beam.
