Park Avenue collection features tops with 1-1/8” thick three-ply balanced panel and solid-core construction that resists warping. Drawer fronts are vertically matched in sets to assure continuous grain pattern. Drawers operate on high-quality, steel ball-bearing suspensions to ensure quiet, smooth, long-lasting operation. Full-extension box and file drawers allow complete and easy access to all contents. All drawers are five-sided construction. File drawers are standard with hangrails. Adjustable hex leveling glides allow floor-standing furniture to be easily leveled without lifting the unit. Glides have a 3/4” adjustable range. Units are sold separately.
