The 0 degree dynamic pivot nub is commonly used as a connection hub for dynamic pivots to create full axial motion ranging from 0-180 degrees parallel to the mounting profile. The 0 degree dynamic pivot nub requires no machining services and can be easily assembled, lending itself to repositioning and reuse. The hardware to mount the nub to a profile is included. The suggested mounting hardware to attach the arm to the nub can be found on the "Suggested Hardware" tab.
