This 4-Door Walnut Finish Office Bookcase Filing Cabinet delivers a balanced blend of display and secured storage suited to professional and personal workspaces, defined by a timeless traditional silhouette anchored to a solid wood plinth base. The floor-standing unit features a structured vertical layout: three left bays split between an upper glass-fronted display section and lower solid-door concealed storage, paired with one full-height right bay that operates as a private, lockable compartment. Clear tempered glass doors framed with aluminum trim occupy the upper display zone, while recessed framed panel solid wood doors enclose lower storage, all fitted with brushed nickel zinc alloy bar pulls for a cohesive, polished look aligned with classic walnut finish aesthetics. Constructed for long-term regular use, the cabinet is built around a high-density fiberboard core clad in walnut wood veneer, with 18mm thick main carcass panels, a 5mm back panel, and a matching solid wood wrapped plinth base. Hardware is manufactured from durable zinc alloy, while swing hinges supporting all outward-opening doors are rated to withstand 80,000 open/close cycles. The veneer surface resists abrasion through 400 revolutions of standard wear testing, and the unit meets E1 formaldehyde emission standards for indoor air quality. Each upper adjustable shelf supports a 30kg static load, with total unit static load capacity reaching 270kg. The keyed cam lock on the right full-height door offers 200 unique key combinations to prevent unauthorized access, ideal for securing confidential materials. Functional design supports flexible organization: three adjustable shelves per upper glass compartment mount via 32mm spaced holes, allowing users to customize spacing to accommodate books, decorative objects, or reference materials. The lower solid-door bays conceal less frequently used items, while the locked right bay stores sensitive files out of public view. This cabinet is well suited for placement behind executive desks in corporate office settings, where it supports visible book and decor display alongside secured file storage. It also functions effectively in home studies or residential home offices, holding personal book collections, household documents, and displayed keepsakes. Procurement teams should note the unit ships across multiple cartons, requires 40 minutes of assembly per set, and weighs 150kg once fully assembled. Planning for secure delivery access and on-site assembly support will help streamline installation.
