The HAIBANG 5-Bay Reddish Brown Executive Office Bookcase Wall Unit, model OF-BC-5BAY-REDWD, delivers a traditional, formal executive aesthetic designed to anchor premium professional workspaces. Its balanced mixed open and closed storage layout creates a polished, structured visual presence: a central open display bay flanked by symmetric side bays, topped with matching solid hardwood crown trim and finished with a coordinated base trim for a cohesive built-in look, suitable for both wall-mounted and freestanding installation. The unit spans 3200 mm wide, 430 mm deep, and 2200 mm tall, with uniformly sized 640 mm wide bays for visual consistency; three tiers of open shelving sit at the center above a bank of three stacked 180 mm tall drawers, while upper side bays feature framed glass doors, and all lower sections hold 740 mm tall solid cabinet doors for concealed storage. The bookcase is constructed for long-term heavy use: its carcass and panels use 18mm engineered wood substrate finished with a 0.4mm reddish wood veneer lacquer, while frame, crown, and base trim are crafted from solid hardwood with matching stain and a clear lacquer topcoat. Glass door panels are 5mm clear tempered glass with wood edging, paired with brushed metallic finish zinc alloy bar pulls and concealed hinges that open 110 degrees for full interior access, rated for 80000 open-close cycles. Drawers operate on cold-rolled steel full-extension ball-bearing slides rated for 50000 cycles, while 25mm veneered engineered wood shelves hold up to 30 kg static load each; interior shelves in enclosed bays support 25mm height adjustment to accommodate items of varying sizes, and four anti-tip brackets are included for secure installation. The unit net weight is 280 kg, backed by a 10-year standard warranty. Designed as a backdrop wall behind managerial desks to hold books and display decor, it is ideal for corporate executive suites, boardrooms, and senior management office areas. For procurement, note that one unit ships across multiple cartons, requires 40 minutes of assembly per set, and supports both wall-mounted and freestanding placement to fit varied office layout plans.
