For ideal chairside ergonomics, the cord of SWERV³ should be wrapped around the arm of the
dental professional, draped around his or her neck, or threaded through the operatory light to manage
its weight⁹. The design of SWERV³ decreases the torque on the cord and allows for better adaptation
of Hu-Friedy Swivel™ Inserts, which also increases rotational control and encourages a lighter grasp.
