Divide vertical spacing into five adjustable gears ranging from 35 cm to 43 cm to hold high capacity detergent bottles below 38 cm in height stably. Expand applicable scenes to bedroom and laundry rooms besides kitchen and washroom to store snacks laundry supplies and personal care products in categories. Coat all steel components with uniform anti rust paint layer to strengthen structural firmness. Install silent sliding rail sets under both upper and lower baskets to pull out storage baskets smoothly and arrange cabinet internal articles neatly.
