OVERTURNING WARNINGS: HEIGHT TO DEPTH RATIOS
IMPORTANT: If the height of the upright exceeds six times (6:1) the space between the upright and the base shoe leveler on a wall unit or between base shoe levelers on a gondola, the system must be secured by one of the following methods. Gondola: For gondolas, base shoe levelers must be anchored to the floor or mandated by your regions seismic engineer Wall: For walls, secured at the base shoe levelers AND upright levelers must be anchored to the floor.

LEVELER SPACING
• To prevent overturning the height of the upright (including extensions) must not exceed the leveler spacing by a ratio of 6:1 when unanchored. • If uprights on wall sections exceed the heights listed, the base shoe and upright levelers must be anchored to the floor or otherwise braced. • Base shoes of free-standing wall sections must be anchored to prevent backward tipping. If upright height to leveler spacing exceeds 6:1, the base shoes and uprights must be anchored. • Contact local building official for anchoring requirements in seismic zones. • Maximum shelf depth cannot exceed base deck depth. • Do not hang peg hooks, shelves, or other accessories on the back side of a wall section or any section without base shoes
