The Fixed Loop Extension is a Fixed Beam Bracket with a longer tube to bring your Beam out further from the tree with a loop on the end to attach cables for more support and reduce the cantilever effect.
The Fixed-Loop Extension is used to anchor the support beam 6” away from the tree to a Garnier Limb/GL® as a fixed point.
This type of bracket is designed to be a fixed/static point, stabilizing your platform that has more than one attachment point, usually in conjunction with a Sliding Beam Bracket.
Also when using Knee Braces that are attached to the same tree, use a Fixed Bracket. Caution! When you have all fixed points in more than one tree. Float your joists, to allow the trees to move and not pull on your treehouse.
