ABSTRACT:
A multiple service fitting for enabling through-floor passage of a plurality of different types of conductors, from a multi-cell underfloor raceway source thereof to an in-floor or above-floor outlet therefor.
A mechanism operable from the accessible end of such fitting enables secure engagement thereof with the top walls of the multi-cell underfloor raceway without moving the fitting body portion, to compensate for floor slab deflection.
A grommet and conduit extending tube, seated in and projecting from the opening in the top wall of the underfloor raceway cell, isolate and protect conductors passing therethrough.
