How does adjustable shelving vs. fixed shelving affect versatility?

Adjustable shelving uses shelf pins or clips in a series of holes along the side panels, allowing shelves to be repositioned in 32 mm increments for different item heights. Fixed shelving uses permanently dadoed or doweled shelves that cannot be moved. Adjustable shelving is recommended for general commercial use to accommodate changing storage needs over time.
