Middle Atlantic Products' new writing shelves are designed to provide a secure work surface, and are available for their WRK or MRK series enclosures.  These shelves feature an attractive 1" thick graphite-marbled laminate surface with a durable black T-mold edging.  The supplied mounting system consists of sturdy steel tubes that attach at both front and rear rackrail in each rack bay and extend beneath each writing shelf providing support.  Additionally, each writing shelf includes cable pass-through holes with grommets providing effective cable management for laptops, computer keyboards, etc.  Each writing shelf precludes the use of two front and two rear rackspaces.
