Adjustable Frame Mount Link Bracket 30 Degree
There were 2 reasons we made them this way. First off we have never had a reported failure with our 3 legged links that are entirely 1/4" so the additional strength helps. Secondly, the inner plate's 3 points of adjustment are each threaded so tightness and bolt retention are incredible. The inner plate is also a tremendous helpful in the mock up stage because of the 5/8" threaded holes.
These are sold individually and these are preset to a 30 degree angle. You can easily get a greater angle with a little fine tuning.
