Fire retardant sleeve

A smoke and fire protection assembly providing a heat sealable raceway through a concrete floor or wall mounting location, said assembly comprising:

• at least one intumescent thermal expansion member having a centrally disposed aperture positioned within a heat conductive shield defined by an outer side wall;
• a tubular sleeve defined by a wall of minimal thickness having an inner surface forming an interior chamber and an outer surface operatively associated with said aperture, said sleeve having a length sized to accommodate thickness of a mounting location;
• means for independently securing said tubular sleeve to the mounting location, wherein said means for independently securing said tubular sleeve is a key out integrated into said outer surface of said tubular sleeve;
• and a raceway formed from a pipe having an interior chamber defined by a wall of nominal thickness and an inlet and outlet demarcating a length greater than said length of said sleeve, said pipe insertable into said sleeve forming a raceway for carrying continuous line items from one room to another, said inlet and outlet of said pipe available for coupling additional raceways at a distance separate from the mounting location.
