Large Lag Bolts
1" x 8"-------- $20
1.25" x 10" ---$25

Lag bolts are not as versatile and do not hold up near the loads that GLs do. GLs are designed to hold the load out away from the tree in shear. The standard GL knee brace holds the wooden load out away from the tree, the load is mostly in compression. Michael does not rate or recommend using the lag for knee braces but others in the industry do.

The 1'' lag can be used to attach the wooden knee brace directly to the tree and used for attaching the suspender to the tree, but again does not hold near as much load as a GL.



 Radial Spline: $60, normally used with a knee-brace, holds a horizontal beam at the tree.

Heavy Duty Double Adjustable Knee Bracket: $250

Used for bigger treehouses and heavier vertical and horizontal loads. This Bracket adjusts both ways in and out and up and down, it adjusts to the angle of the tree and the distance between GL's. For the top GL you need at least 12" of perch. We recommend the 24" GL with 14" Perch. For the bottom GL we recommand the 12" GL with 6" perch. (GL's are sold separately)

Used for any time you have a knee brace attached to same tree and to stabilize a platform that has more than one attachment point. If you have 4 trees you can have one tree that is fixed. Usually the largest and one that moves the least. The others need to be sliding so all trees independently from each other.
