The Standard Limb Dynamic Uplift Arrestor is one of our most common accessories to the TAB. The "DUA" lets the tree move and grow a significant amount. It does this by allowing the beam to "slide" within a range of lateral movement while still holding the beam in place. This allows for the treehouse to move naturally with the tree.
The Dynamic comes with an installed nylon pad, two 3/4" x 5" galvanized lag screws to attach the Dynamic to the beam, and a rectangular steel sheath to slide over the Standard Limb TAB end.
