NESCO's Duct Seal remains flexible over time and resists cracking or shrinking, even in temperature fluctuations. Its moldable nature allows it to conform tightly into irregular openings or tight corners, forming a tight seal without the need for tools. Its especially useful for sealing around conduit or cable penetrations into electrical panels or junction boxes, and it wont drip or run, making overhead applications clean and manageable. It can be easily removed and reused when needed.
