The Tree Fort Dynamic Uplift Arrestor (DUA) fastens a Nelson Treehouse Tree Fort TAB to the bottom of a beam while still allowing 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.
Package Includes: (1) Slider bracket, (1) Nylon Slab, (2) 5/8" x 4" lag screws, (2) 2" wood screws, and (1) T-20 Bit
