Identify the narrowest points on the delivery path: building door, lift door and car, corridor turn and final doorway. Measure clear width, threshold and turning space.
Include wheels, handles and projections in the container's outside dimensions. Check lid clearance too, then trial an empty unit on the real route if measurements allow.
If handling or loaded weight affects passage, repeat with a representative load. Link measurements and photos to the model and record the purchase decision.
