2-Pack Expandable Kitchen Cabinet Shelves: Stackable and adjustable compact storage racks. Each unit measures 52 cm in length and supports a load capacity of 10 kg. Constructed from chrome-plated carbon steel wire and ABS plastic connectors. The metal wire components are straightened, bent, and resistance-welded into shape before undergoing chrome plating; the plastic connectors are produced via injection molding. The expandable structure allows for length adjustment via plastic sliding clips located on both sides. Stackability is facilitated by interlocking grooves situated at the top of the vertical support posts. Manufacturing utilizes automated welding machines and injection molding equipment, with manual assembly required to snap the components into place. Suitable for organizing canned goods and spice bottles in pantries or on countertops.
