Abstract: A modular outlet box 40 is used in a raised or access floor assembly 30 together with standard support modules 86. The modular outlet box 40 has a central base panel 42 with openings 44 in which a duplex receptacle assembly 2 or a dual communications outlet 10 can be mounted. Inclined side panels 60 extend between the base panel 42 and a peripheral bezel 72 that extends around the modular outlet box 40. Openings 62 in these side panels 60 are dimensioned to receive cable mounted RJ communications jacks 14 and MT-RJ fiber optic connectors 24. SC fiber optic connectors 18 can be mounted in channels located on the ends of the base panel 42.
