Mid-Size 3-Drawer Black Steel Filing Cabinet - Departmental A3/A4/F3/F4 Lockable Office Storage (D-D3)

Mid-Size 3-Drawer Black Steel Filing Cabinet — Departmental A3/A4/F3/F4 Lockable Storage (D-D3)

Occupying the versatile mid-point in CBNT's black steel drawer cabinet series (available in 2, 3, and 4-drawer configurations), the D-D3 is the ideal 3-drawer departmental filing hub — powerful enough to serve an entire team yet compact enough at 1015 mm tall to integrate seamlessly beside standard office desks. Its mid-profile height positions the top drawer at a natural standing-reach level while keeping the cabinet silhouette below seated eye lines, preserving the visual openness essential to modern open-plan workplaces. Available in two configurations — a 465 mm-wide drawer slot model (620 mm depth, optimized for EU/US markets) and a 470 mm-wide hanging rod model (600 mm depth, ideal for global distribution) — each unit accommodates A3, A4, F3, and F4 documents. Individual label frames on all three drawers enable instant content identification across team members, while the central locking system secures the entire cabinet. Finished in a signature matte black electrostatic powder coat with fully customizable handles, the D-A3 is the go-to filing solution for department clusters, manager offices, and shared team workspaces.

Our Advantages

A. The Departmental Sweet Spot — 3 Drawers at the Ideal Shared-Use Height
At 1015 mm tall, the D-A3 occupies the functional sweet spot in the black series lineup — substantial enough to serve as a shared departmental filing hub for 3-6 colleagues, yet compact enough that its top surface doubles as an impromptu standing-height workspace for quick document review. The three drawers naturally segment into an intuitive filing hierarchy: top drawer for daily active files, middle for weekly reference materials, bottom for daily active files, middle for weekly reference materials, bottom for monthly archives. This built-in organizational logic makes the D-A3 the most intuitive cabinet in the series for multi-user environments where multiple people access the same cabinet throughout the day.

B. Label Frame Organization System — Instant Visual Identification Across Teams
All three drawer fronts on the D-A3 feature integrated label frames — a small but transformative feature in shared office environments. Teams can label drawers by document type ("Invoices Q1-Q2", "Personnel Files A-K", "Project Archive 2025"), by owner, or by access frequency. This visual labeling system eliminates the time-wasting ritual of opening multiple drawers to locate files — a friction point that compounds significantly in departmental settings where 5+ people interact with the same cabinet daily. For legal firms, accounting departments, and HR teams managing high document turnover, the label system turns the D-A3 from passive storage into an active filing workflow tool.

C. Regional Market Optimization — One Product Family, Two Precision Specs
The D-A3's dual-configuration strategy is built on real-world export data:
- 465 mm Slot Configuration (620 mm depth): This narrower, deeper variant is engineered to European and North American preferences — where hanging folder systems benefit from maximum drawer depth and the 465 mm width integrates smoothly with metric-based modular office furniture systems common in EU markets.
- 470 mm Rod Configuration (600 mm depth): A slightly wider body with hanging rod rails, delivering versatile 600 mm depth. This variant is optimized for buyers across Asia, the Middle East, and Africa — markets where the additional 5 mm width accommodates regional file folder dimensions more comfortably.
Both share identical height, lock system, and finish — a single family for global distribution.

D. Professional Matte Black & Custom Handle Options for Wholesale Buyers
- Signature Matte Black Finish: Durable electrostatic powder coating in a fingerprint-resistant matte black — projects professionalism across any office interior. Full RAL color customization available for bulk orders.
- Customizable Handle Selection: Bar handles, arch pulls, slotted grips, or wire pulls — select the handle style that matches your brand or client preference.
- Knock-Down (KD) Structure: Flat-pack shipping reduces container volume by up to 60% — mix D-A2, D-A3, and D-A4 in one shipment.
