The standard straight dynamic pivot arm is typically used to create a dynamic pivot between profiles; it provides a long-lasting connection and requires no machining services. The pivot arm can be easily assembled, lending itself to repositioning and reuse and has a permanently lubricated bronze bushing that acts as a high-strength pivot point. The hardware to mount the pivot arm to the profile is included. The suggested mounting hardware to attach the arm to the nub can be found on the "Suggested Hardware" tab. Tip: Pre-load your hardware prior to connecting profiles to simplify your assembly and save time.
