The Heavy Limb Static Uplift Arrestor is used along side the Heavy Limb TAB. The "HL SUA" allows for tree growth while holding the beam in place. Used mostly for one tree treehouses. In the case of multiple trees, a combination of Dynamic Uplift Arrestors, and SUA's are recommend.
Static is installed with two 3/4" x 5" galvanized lag screws (included with purchase; not shown).
