Making full use of high cabinet space in the kitchen has always been a challenge. Items stored deep inside are difficult to reach, bottles and jars often become cluttered, and finding the right item can take a lot of time. These problems are common in many households.

The Welldo A661 High Cabinet Door-Linked Pull-Out Storage System is designed to solve these storage challenges. Featuring an innovative door-linked pull-out mechanism, when the cabinet door is opened, all internal shelves smoothly slide out together, bringing every item stored in the deepest part of the cabinet within easy reach.
Whether it is dry goods, spices, snacks, and beverages in the kitchen, or wine bottles and glassware in a dining cabinet, the A661 system provides an organized and efficient storage solution, keeping everything neatly arranged and easily accessible.
Founded in 2005, Welldo (Guangzhou Welldo Hardware Manufacturing Co., Ltd.) is one of the professional manufacturers in China specializing in the design, production, and sales of high-quality kitchen cabinet hardware accessories. With a factory area of approximately 6,000 square meters, Welldo is committed to providing reliable storage solutions for global customers.
The A661 series is one of Welldo’s core products in the high cabinet pull-out storage category. With excellent craftsmanship, stable quality, and practical design, it has gained the trust of kitchen cabinet manufacturers, distributors, and engineering projects both domestically and internationally.
The A661 adopts an innovative door-to-internal-frame linkage structure. When the cabinet door is opened, the shelves are connected through a linkage system and smoothly slide outward together. Compared with traditional fixed shelves, the full extension design allows you to easily access items stored deep inside the cabinet without reaching in, making every corner of the high cabinet fully accessible.

The A661 features storage baskets on both the cabinet door side and the cabinet interior side, creating a double-sided storage layout. The door side is ideal for organizing small items such as spices and cling film, while the inner shelves can store bottles, jars, and dry goods — opening one cabinet door provides double the storage capacity.
Equipped with a premium silent sliding system, the product ensures stable, smooth, and quiet movement during operation. After rigorous laboratory testing, the slides maintain excellent performance after more than 20,000 repeated pull-out cycles, ensuring long-lasting durability.
The A661 uses a thickened metal frame with high-strength welding technology, providing a stable structure that remains strong and durable over time. The baskets feature a three-layer anti-rust coating treatment, ensuring a clean appearance and easy daily maintenance.

Height Adjustable: The basket height can be adjusted according to different storage requirements.
Left & Right Universal Installation: The opening direction of the cabinet door does not matter — the system can be installed on either side.
Multiple Configurations Available: Available with 4 to 6 shelf configurations to fit different high cabinet heights and storage needs.
The A661 series includes four models, all designed for 450mm wide high cabinets.

Fix the bottom slide onto the cabinet base panel and ensure the slide remains level.
Install the door linkage bracket on the inner side of the cabinet door and align it with the internal slide system.
Assemble the metal frame and storage baskets according to the installation position. Adjust the spacing between shelves according to storage requirements.
Fix one end of the connecting rod to the door linkage bracket and connect the other end to the main frame. This is the key step that enables the door-linked pull-out function.
Push the assembled system into the cabinet, close the cabinet door, and check whether all shelves are fully aligned. If necessary, make fine adjustments through the adjustment screws.
After confirming the correct position, tighten all fixing screws. Open and close the cabinet door 3–5 times to test the smoothness of the sliding system and the synchronization of the linkage mechanism.
