Products Description

Expandable Width for Different Cabinet Sizes
The lower shelf expands from approximately 31 to 50 cm, allowing the organizer to serve narrow and wider cabinet interiors. This adjustable footprint gives buyers a stronger product positioning for kitchens, bathrooms, laundry rooms, and utility cabinets with different internal dimensions.
Two-Tier Organization for Mixed-Size Items
The lower shelf provides a broad storage area for bottles, containers, and larger products, while the upper baskets are suitable for smaller boxes, jars, rolls, and frequently used accessories. This vertical arrangement improves category separation without requiring additional floor space.
Three-Level Height Adjustment for Flexible Layouts
The vertical frame offers three height positions, enabling the upper storage level to be adjusted according to the cabinet interior and the products being stored. Buyers can present the organizer as a flexible solution for cabinets with different heights or fixed internal obstructions.
Expandable Structure with Retail and Packaging Advantages
The expandable frame provides configuration flexibility while the detachable components support easier packing and assembly. The product information shows a compact package format with a carton size of approximately 52.5 × 41 × 33 cm for five pieces per carton, subject to final packaging confirmation.

Product Details

Expandable Width with Guided Storage Movement
The lower shelf uses an expandable structure to adjust the storage width while maintaining a defined basket perimeter. The sliding rails guide the shelf forward when users need access, changing the storage process from reaching deep inside the cabinet to pulling the contents toward the front. This combination is suitable for cabinet interiors where width varies but forward access remains important.
Three-Position Height Planning Around Cabinet Obstacles
The vertical support frame provides three height positions for the upper baskets. This allows buyers to plan the storage layout around plumbing, cabinet partitions, or different product heights. Taller bottles can remain on the lower level, while smaller and frequently used items can be arranged above for easier visibility and access.
