Magnarok Cable Sealing Cement provides an extremely dense, high-strength filler that seals all openings around electrical cables and positively prevents the transmission of flames, smoke and/or water through deck or bulkhead penetrations in marine applications. It is a United States Coast Guard "accepted" cable sealing product for through-penetration fire stop designs. Magnarok Cable Sealing Cement is supplied as a dry powder that when mixed with water achieves high early strengths, slight expansion and long term non-shrink properties.
