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

lags are not as versatile and do not hold 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 for attaching the suspender to the tree but again does not hold near as much load as a GL
