RectorSeal has introduced the Metacaulk Cast In-Place Device (CID) for firestopping HVAC, plumbing and electrical piping, and cabling through-penetrations in new construction concrete and concrete-over-metal-decking floors. The CID carries Underwriters Laboratory (UL) testing and approval to UL 1479 for an F-rating of up to three hours and temperatures reaching a minimum of 1,800°F (982°C). The product line consists of 8-inch-tall (20-cm) CIDs available in construction trade size 2-, 3-, 4-, and 6-inch-O.D. (5-, 7.5-, 10-, and 15-cm). Each size accepts as many 4-inch-long, quick snap-fit extensions as needed for any concrete floor depth.
