The KETAI Traditional Mahogany 6-Door Office Bookcase, model OBC-6D-MAH-2400, is a purpose-built commercial storage solution defined by classic, formal styling balanced with functional design. Visually, the unit is structured into two distinct horizontal zones: an upper display section reaching 1100 mm in height, fitted with clear tempered safety glass doors, and a lower 900 mm concealed storage section with solid, mahogany-veneered doors. Six equally sized 400 mm wide doors span its full 2400 mm width, creating a symmetrical, streamlined silhouette that complements traditional office aesthetics, while its modular design supports flexible layout integration alongside matching office furniture pieces. Constructed for long-term commercial use, the bookcase is built from E1 grade MDF with a density of 0.75 g/cm³, with 18 mm thick carcass panels, 20 mm thick door panels, and a 5 mm thick back panel. All visible surfaces are finished with 0.6 mm mahogany or red walnut wood veneer, coated in scratch-resistant polyurethane wood paint to withstand regular office wear. Hardware includes zinc alloy lever handles, steel cam locks, and damping steel hinges rated for 120,000 open/close cycles, with steel shelf pins fitted to multi-position adjustment holes for flexible shelf placement. Functionally, the unit combines open display and secure storage: the upper glass-door zone contains five compartments for visible access to frequently referenced materials, while the lower section holds six lockable compartments secured by keyed cam locks for sensitive document storage. Internal shelves adjust to multiple vertical positions, with a 350 mm maximum vertical clearance to accommodate upright ring binders, and support a 30 kg distributed static load per shelf, with a 45 kg maximum per-shelf static load capacity. Hinged doors open 110 degrees with soft-close damping to prevent slamming and reduce operational noise. The unit includes a required wall anti-tip restraint rated for 100 kg to support stable installation. This bookcase is ideally suited for executive offices, meeting rooms, and administrative document storage areas, designed to hold archived documents, reference books, upright ring binders, and general office supplies. For procurement planning, note the unit ships across multiple cartons, requires 40 minutes of assembly per set, carries a 5-year standard commercial limited warranty, and has a net assembled weight of 120 kg. Specifiers should confirm on-site assembly support and appropriate wall anchoring capabilities prior to installation to meet workplace safety requirements. Total packaged volume per set is 0.65 m³, for logistics and delivery space planning.
