The RSIC-1 ADM is intended for use under a concrete slab or steel deck floor system, for a dropped drywall ceiling. The RSIC-1 ADM is fastened directly to the underside of the concrete using a 3” or 4” drive pin supplied by PAC International, Inc. A threaded cup washer is then installed to the pin, then the RSIC-1 ADM is threaded onto the drive pin, and set to height. The RSIC-1 ADM will boost the Impact Isolation Class (IIC) of the assembly by up to 20 IIC pts and 10 STC pts.
