Do you need replacement support arms?
We have a few different upper-parts and track styles. The tracks can go onto the upper part facing forward or backward... so pay attention to the picture's associated to each option.
Reach out to support@pwncnc.com and we're happy to identify the exact style you own.
Note that this is NOT the entire bracketing system... only the support arms which are provided for those who broke theirs.
Bracketing systems can be found here: https://pwncnc.com/products/z-independent-bracketing-system
