36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

Comment. The proposed rule specified that call buttons be located 35 to 48 inches above the floor (407.2.2). These controls should be held to the basic reach range specifications in section 308 like any other operable part, according to commenters.

Response. In the final rule, call controls are required to be located within one of the reach ranges specified in section 308 (407.2.1.1). In addition, the Board has removed a requirement that objects mounted beneath hall call buttons protrude no more than 4 inches into the clear floor space. Such protrusions are adequately addressed by requirements for clear floor space in 305 and for protruding objects in section 307.
