Wall-Mounted Objects

Proper cane and service animal techniques allow people to walk along a corridor or path without bumping into walls. Overhangs that are above cane sweep height may protrude 4 inches without being hazardous. Objects within the sweep of canes (at or below 27 inches) or above 80 inches can protrude any amount.

Diagram showing protruding object requirements for wall-mounted objects

Wing walls, side partitions, and alcoves or recesses can be used for elements such as drinking fountains with their bottom edges above 27 inches. Fixed elements or barriers can provide detection below objects not required to have knee or toe clearance.
