The 90 degree double pivot bracket assembly with "T" handles is commonly used to add motion to certain elements of your project. It is comprised of one 90 degree left hand pivot bracket, one 90 degree right hand pivot bracket, two "T" handles, and one 0 degree structural pivot nub. The shoulder bolt and nylon thrust washers are also included. The brackets have permanently lubricated bronze bushings that act as high-strength pivot points.
