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.

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.
Really great product. The dust collection exceeded my expectation!
