R407       *BUMPERS shouldn’t be wedges. BUMPERS must not act as wedges when interacting with other BUMPERS.

Examples of BUMPERS which might act as a wedge, and may invite additional scrutiny, include:

A.      BUMPERS utilizing softer foam towards the top of a BUMPER profile,

B.      BUMPERS utilizing excessively rounded profiles such as a single semi-circle, and

C.      BUMPERS with tapered or stepped padding such that the padding is thinner or thicker towards the top or bottom.

Rule R406
R406       *Fill BUMPER corners. Corner joints between BUMPERS must be filled with uncompressed padding material extending at least 2.25in (5.72cm) from the corner with no gaps or voids. Examples of implementation are shown in Figure 8‑10.
Rule R405
R405       *BUMPERS interact with BUMPERS. While navigating the FIELD normally, all BUMPERS must have padding (per R402-A) supported by backing (per R402-B) entirely filling the BUMPER ZONE, a space between 2.5in (6.35cm) and 5.75in (14.61cm) from the floor.
