Abstract
The service fitting may be installed in the floor of a structure. It enables activation of power, communication, and/or data services at the fitting location. It includes wedge locks, which releasably engage the floor opening. The wedge locks are operable from above the floor, to engage with and release from the floor opening. Upon engaging the floor opening, they resist unauthorized upward pulling of the fitting. Upon release from engagement, they enable authorized removal of the fitting, without requiring potentially damaging efforts for access thereto through a limited access ceiling of the floor below. The fitting further includes elements for retarding transmission of fire through the floor opening and the fitting. They maintain the fire rating of the floor at substantially the same level with or without the floor opening and fitting in the floor.
