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. An ultra high molecular weight polyethylene (UHMW) slab provides a surface for the Tree Fort TAB to slide freely. This allows for the Tree Fort to move naturally with the tree.
