Levers and the ADA:
 Levers have become the standard lock trim, due to the Americans with Disabilities Act (ADA). Knobs require grasping and twisting, whereas levers can be operated without hands. In addition, many manufacturers have made "free wheeling" or clutch-type levers, which are designed to take the abuse and vandalism that levers are subject to. See manufacturers' options for more information.
