Information: Treehouse Hardware

Treehouse hardware: an overview

The Nelson Treehouse science of building safely and sustainably up in the trees is founded on the use of the highest-quality, heavy-duty, specialized treehouse hardware. We have spent over 30 years consulting with and working alongside carpenters, arborists, and engineers to develop the hefty hardware we trust in every treehouse we build.

In 2016, we tested the weight-bearing capacity our Treehouse Attachment Bolts (TABs) at the Composite Materials and Engineering Center at Washington State University. The ICC-accredited results proved just how strong our TABs and the associated hardware are when properly installed in the tree(s). 


Our treehouse hardware is fabricated in the USA and is comprised of heavy, heat-treated steel – a single standard-limb TAB weighs 18 pounds. It’s professional-grade, but DIY-friendly: hundreds of backyard treehouse-builders around the world have used our hardware to create the treehouse of their dreams.


We’re here to support you along the way: we offer consultations via phone or in-person to advise DIY-ers on their treehouse projects. From quick questions, to more in-depth problem solving, to modification of our existing plans, we're here to help. When you purchase any of our treehouse designs and/or hardware, we provide a complimentary 15-minute consultation to advise you on the necessary equipment for your project.


Importance of using specialized treehouse hardware

Unlike a traditional earthbound house, the foundation for a treehouse is elevated in the air and rests in living organisms. Yet treehouses are not lightweight structures: a fully finished, furnished, and occupied treehouse can weigh tens of thousands of pounds. The foundation for the treehouse – its connection to the trees and the hardware that supports its prodigious weight – is of the upmost importance for the safety of the occupants, health of the tree(s), and longevity of the structure.


When properly installed, our treehouse hardware provides a safe, sustainable, and strong support system for your treehouse without causing irreparable damage to the trees. Investing in quality, specialized hardware is essential for creating an enduring foundation for your treehouse.


In most of our treehouse builds, we install heavy-limb hardware, as we are typically building large-scale treehouses with extensive square footage and weight. For DIY-ers building a modest backyard treehouse, standard-limb hardware will usually be adequate.
