The 90 degree dynamic right angle pivot nub is commonly used as a connection hub for dynamic pivots to create full axial motion ranging from 0-90 degrees perpendicular to the mounting profile. This 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.
