Extensions
Handrails that are not continuous must have horizontal extensions at both the top and bottom of the ramp at least 12 inches long that are rounded or returned smoothly to walls, posts, or floors. Inner handrails on switchback ramps must be continuous. Handrail extensions are required on all new ramps but need not project into perpendicular circulation paths in alterations. ADAAG (Figure 17) illustrates returns to post that comply as protruding objects.
