12 FT OCTAGON TREE HOUSE KIT
It’s time for your family to have fun in the trees! There is room for everyone to get up in the tree house and enjoy being a kid again. It could even be a quiet place to just go read a book or see nature up close.
This kit includes all the specialty hardware you need to build our 12′ Octagon Tree House Plan (plan included):
- 2 – TAB* 3×9 Bolts with nuts
- 2 – 1.25″ Pipe Brackets
- 6 – 1.25″ single Knee Brace Brackets
- 6 – 1.25″ x 12″ Galvanized Lag Bolts
- 12 – 5/8″ Carriage Bolts with flat washers, lock washers & nuts
*TAB – Tree House Attachment Bolt
All of the TABs are based upon the original design specifications by Greenwood Engineering in the Stud Tree Fastener 9STF) diagram. Some versions such as the TAB 3X6 HP and the TAB 6×9 HP are larger, but the machining process and most of the other specs are the same as the original Tree house Attachment Bolt (TAB 1×6 HP) which is very similar to the STF. One difference is ours are 4 threads per inch instead of 5, which installs faster and grabs the wood better.
Please remember that our fasteners do no have weight ratings. The actual weight they will hold depends on the species of the tree, the tree’s ongoing health, the distance the load is placed from the tree, the depth to which the collar is installed, whether or not the end of the fastener is backed up higher in the tree with a suspension system, and other design specific factors. Please consult your professional engineer, arborist, or experienced tree house builder to ensure that you choose the right fasteners for your tree house project. Safety is #1
