What aids in weight distribution when using fillers or lock-in on shelves?

• A. Wood Blocks
• B. Natural T's Or Bridges
• C. Metal Braces
• D. Cardboard Filler Only

Answer: (B)

Weight distribution on shelves hinges on creating a load path that spreads force across more contact points and into the uprights. Natural T's or Bridges act as load-spreading elements because they bridge across the shelf and tie filler sections together. This bridging distributes the weight over a wider area, reducing concentrated stress on any single point and minimizing sag or shifting. By connecting multiple supports, these pieces help the shelf act as a stiffer, unified unit, keeping items stable and the system safer when you fill gaps or lock items in. Other options tend to concentrate load (wood blocks), lack sufficient strength for heavier loads (cardboard filler), or don’t provide broad distribution across the span the way a T-shaped or bridge element does.
