Bracketing Systems are a complete set of parts... basically the plastics, tracks, arms, thumb screws, locking pins, and screws to mount onto the specified CNC machine.

Special Notes: Onefinity has released a new Carriage called the Z-20. This new carriage comes standard on their Elite machines while the older carriage they've called Z-16. Be sure to choose the correct option when purchasing bracketing as there are important differences between them.

Up/down Z movement is somewhat "jerky"; it does not move smoothly. Bit mouth opening is not wide enough to take a larger surfacing bit.
The only thing I’d like to have little different is longer legs so the dust boot can hang lower when the spindle is mounted at its highest position, maximizing Z height. I just printed longer legs on my own. They’re a very simple part, so it’s great to print these locally, as they also get broken from time to time.
Z-Independent Bracketing System
Very well machined great fit
It works fine, but if it’s all the way down, it hits the rail and stops the machine when it is homing or all the way in the left corner.
