Advisory 11B-609.3 Spacing. The distance between the grab bar and wall is an exact dimension. Many disabled people rely heavily upon grab bars to maintain balance and prevent serious falls. Many people brace their forearms between supports and walls to give them more leverage and stability in maintaining balance or for lifting. The grab bar clearance of 1½ inches required in this section is a safety clearance to prevent injuries resulting from arms slipping through the openings. It also provides adequate gripping room.◼
A grab bar is shown with a projecting object mounted above and below it. Projecting objects must spaced 1½ inch minimum below and 12 inches minimum above the grab bar. Recessed objects can be spaced immediately above and below.
