Building A Tree House

By Robert Robillard on How To

The stem of the TAB bracket is designed to support different tpes of cradle brackets. The cradle or “floating” bracket is what we secure to our treehouse frame.

Treehouses are subject to frequent load reversal produced by winds, as a result TABs are made of 4140 Carbon Steel.  TABs are able to support from 9,000 and 12,000 pounds (4,100 and 5,400 kg),and boast a greater strength load than conventional lag bolts.

Once the tab is installed the tree to grows around the TAB, making it stronger.

Installing the TABS

The TABs need to be installed according to the manufactures recommendations. Don’t install TABs in trees with a diameter las than 12”.

You’ll need the following tools to install this right:

  • High torque drill
  • Large ratchet / socket
  • Torpedo level
  • 3” self-feeding bit
  • 1-1/8” x 16” auger bit
  • Cheater pipe or socket

To install our tabs we first drilled the larger 3-inch hole, then the smaller, deeper hole.  It’s important to drill your hole level into the tree.

Once the holes are drilled we hand screwed in the TAB as far as we could, then finished it with a large ratchet, socket, with the help of a cheater pipe for leverage.

We determined our height of our floor and subtracted to get the height of the TAB. Once we drilled the first TAB we used a straight 2xg and a 6-foot level to locate the second tree TAB.
