Prevents Dust, Debris and Moisture from Damaging Rack-Mount Equipment from AboveThis SmartRack® Service Entrance Hood provides cable management and environmental protection at the same time. The black sheet metal hood mounts to the top of your full-size rack enclosure, allowing equipment cables to enter the rack without letting in water, dust and other debris. The SRSEHOOD covers the cable access holes on the rack’s top panel and mitigates infiltration of moisture into the rack. Mounting hardware and rubber gasket material are included.
