How far can objects with leading edges between 27 inches and 80 inches above the floor project into a circulation path?

Objects with leading edges between 27 inches and 80 inches above the floor can project into a circulation path a maximum of 4 inches. This guideline is in place to ensure safety and accessibility for all individuals using the circulation path, including those who may be blind or visually impaired.

A projection of 4 inches is considered acceptable as it allows sufficient clearance and prevents potential obstacles that could cause accidents or impede movement. This further aligns with accessibility standards, which aim to maintain free and unobstructed pathways in public spaces.

In contrast, the other distances provided, such as 1 inch, 2 inches, or 6 inches, do not adequately accommodate the need for safety and accessibility. A projection greater than 4 inches could pose dangers in a busy circulation path, while a projection less than 4 inches may not be in line with the design requirements that consider the height and movement of different users.
