SpecSeal® SSP Firestop Putty excels at sealing cabling penetrations and outlet boxes. SSP Putty is non-hardening and easily hand works around grouped cabling penetrations forming a re-enterable seal allowing for future work. When applied with outlet boxes, SSP Putty easily works into voids and seams forming a continuous seal against fire and the products of combustion.
