This Narrow Metal Vertical File Cabinet is an essential addition to any office or home, offering high capacity and easy organization. With four spacious drawers featuring fully retractable ball bearing slide rails, accessing your files is a breeze. The adjustable hanging rods in the file drawers accommodate A4, Letter, or Legal size folders, ensuring your documents are well-organized and maximizing storage space. Security is a top priority, with a single lock securing both drawers simultaneously, and two keys included for added convenience. The anti-tilting mechanism ensures that when one drawer is open, the other remains locked, preventing tipping and safeguarding your files and workspace. Made from high-grade cold-rolled steel, this all-steel structure is more robust and durable than wooden alternatives. Its smooth surface coating is waterproof and easy to clean, while being environmentally friendly with zero formaldehyde, protecting your health and the planet. The humanized design includes steel ball bearing full extension drawer slides for quiet operation, maintaining a peaceful work environment. The extra-long drawer handles enhance convenience, even in tight spaces. Assembly is simple, with clear instructions and an assembly video available via a QR code. If you encounter any issues, such as drawers being too high to close, it's likely due to a poor connection between the drawer and rails. Reinstalling the drawer and ensuring it’s securely fastened to the rail snaps will resolve the issue.
