This suspension plate has a nut welded into it so that it can turn onto the treehouse attachment bolts that are sold on this website. The hole faces upward to accept the pin of a turnbuckle or shackle or a thimble. Then a cable or chain lifting system can be attached to support the end of the bolt. The purpose is to remove the leverage from heavy loads or normal loads that are place far out onto the perch.

• These tree house brackets are used to back up Treehouse Attachment Bolts when the loads are large or placed far out on the perch. When installed properly and connected to a point higher in the tree, they remove leverage from the load equation on theTAB up to the strength of the upper attachment, which can reduce the likelihood of attachment failure. Please consult with your professional engineer, arborist, or experienced tree house builder to ensure that you choose the right fasteners for your tree house project. Safety is #1.
