Why are lever locks replacing the use of knobs?
The Americans with Disabilities Act (ADA) created a list of requirements that new construction must meet to accommodate disabled citizens. The state of Tennessee has adopted the North Carolina Handicap Code. This code calls for all H.C. accessible doors to be operated by a device with a shape that is easy to grasp, and it should not require tight grasping, tight pinching, or any wrist motion. Levers are used to accomplish this requirement.
