Stack-on storage adds overhead storage to L-shaped workstations formed from credenzas or returns in the HON 10700 Series Laminate Wood Desk Collection. That collection offers an upscale contemporary design, elegant lines, stylish accent details, durable laminate surfaces and quality construction. Premium, multi-layer, high-pressure, Cognac laminate surface resists water, scratches and most solvents. Hardwood accent trim is produced using a multi-step finishing process and adds an elegant touch appropriate for upper-management offices. Inside storage includes two 34-3/4" wide x 12-7/8" deep x 12" high compartments. Stack-on storage is also equipped with self-closing, adjustable hinged doors, and valance to hide a task light (sold separately). Clearance between storage and your worksurface is 19-3/4". Attach to the desk, peninsula or corner unit via double-sided tape and to the return through the grommet hole.
