Components of the Park Avenue Collection’s U workstation feature tops with 1-1/8” thick three-ply panel and solid-core construction. Balanced panel construction resists warping. Adjustable hex leveling glides with 3/4” adjustable range allow floor-standing furniture to be leveled without lifting the unit. Two cord management grommets, for routing and hiding wires and cables, are located in the end panels of all desks. Component tops and backs are not to be used freestanding. Component tops and backs/modesty panels must be used in conjunction with modular pedestals, measure 1-1/8” thick and provide finished back for modular pedestals or an enclosed kneewell. End panels support the end of a component top if no modular pedestal. To accommodate the modesty panel, end panel depth is 3/4” less than the depth of the component tops. Cannot be used as return or desk shells. Meets or exceeds ANSI/BIFMA and ISTA performance standards.
