The standard 90 degree dynamic pivot assembly with straight and "L" arm is typically used to create dynamic pivots that are perpendicular to the mounting profile and have full axial motion ranging from 0-180 degrees. The assembly includes one 90 degree dynamic pivot nub, one standard straight dynamic pivot arm, and one "L" dynamic pivot arm. It has permanently lubricated bronze bushings that act as high-strength pivot points and nylon thrust washers that protect the pivot arms. The hardware to connect the nub to the profile, the nub to the arms, and the armsto the profile are all included.
