2. Steel Sleeve (Optional) nom 22 in. diam (or smaller) cylindrical sleeve formed from min 1/8 in. thick steel. Length of steel sleeve to be 1-1/2 in. greater than thickness of floor or 3 in. greater than thickness of wall. Steel sleeve to project 1-1/2 in. beyond top surface of floor or both sides of wall.

3. Through Penetrant One metallic pipe or conduit to be installed either concentrically or eccentrically within the firestop system. The annular space between the through penetrant and the periphery of opening shall be min 0 in. (point contact) to a max of 1-3/4 in.

4. Packing Material When optional steel is used, min 5-3/4 in. thickness of min 4 pcf mineral wool batt insulation firmly packed into annular space as a permanent form. When steel sleave is not used, min thickness of mineral wool is 4-1/4 in. Packing material to be recessed min 1/4 in. from top of sleeve or concrete in floor or from both ends of sleeve or concrete in wall as required to accommodate the caulk fill material (Item 5).

5. Fill, Void or Cavity Material* — Caulk When optional steel sleeve is used, fill material applied to fill the annular space to a min depth of 1/4 in. flush with the top edge of steel sleeve in floor or both ends of steel sleeve in wall. When optional steel sleeve is not used, fill material applied to a min depth of 1/4 in. flush with top surface of floor or with both surfaces of wall. A min 1/4 in. diam bead of caulk shall be applied to the edge of the steel sleeve or concrete where the pipe or conduit is installed at point contact. RECTORSEAL — Biostop 500+
