The Tree Fort Dynamic Uplift Arrestor (DUA) is a treehouse beam mounting bracket designed to secure your platform while still letting the tree move naturally. The DUA fastens a Tree Fort TAB to the underside of a beam and uses a durable nylon sliding slab so the TAB can glide as the tree sways and grows—helping reduce stress on your structure and hardware.

• Purpose: Secures beam while allowing independent tree movement
• Compatibility: Designed to work with the Tree Fort TAB
• Movement system: Low-friction nylon slab provides a smooth sliding surface
• Mounting: Attaches to the bottom of a beam with included hardware

Ideal for: DIY tree forts and treehouses where you need a secure beam connection without “locking” the platform to the tree’s natural motion.
