Fixed Extension for extending
The Fixed Extension is Bracket is designed to anchor the support beam to a Garnier Limb/GL® 6"s away from tree for more growth . Making a fixed or static point adding stability to a platform. When the load is farther away from the tree you have a greater cantilever effect and may need additional hardware for more support on a GL®.
An example of use in a 4 tree treehouse one tree is always fixed. Usually the largest or the one that moves the least. The other trees need to be sliding so trees move independently from each other.
Another example is 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.
