Tree Fort Dynamic Uplift Arrestor
The Tree Fort Dynamic Uplift Arrestor (DUA) fastens a Tree Fort TAB to the bottom of a beam but allows the tree to move independently from the platform. A nylon slab provides a surface for the Tree Fort TAB to slide freely. This allows for the Tree Fort to move naturally with the tree.
Includes:
(1) Nylon Slab
(1) Slider bracket
(2) 5/8" x 4" lag screws
(2) 2" wood screws
*After your purchase is complete, you will be provided with installation instructions. Please see the "order note" in your confirmation email to access these.
Components of a Dynamic Uplift Arrestor
To achieve the dynamic movement in the trees, a Nylon Slab is placed in between the TAB and beam. The TAB is then secured with a Metal Bracket using (2) 5/8”x4” Galvanized Lags.
Allowing For Tree Movement
Trees are alive and dynamic - meaning they move independently in the wind and grow in girth.
Preventing natural motion is not only harmful to the tree, but potentially catastrophic for the structural integrity of your treehouse.
Use Static Uplift Arrestors and Dynamic Uplift Arrestors to control platform movement in the trees. This can also be done using Static Yoke Kits and Dynamic Yoke Kits.
