Sealing STOPPER M16 - M40Sealing plugs with ECON® technology, for sealing all common electrical installation pipes in installation boxes or on line outlets. The long seal socket with three sealing lips and different widths adapts to the respective installation pipe and guarantees the airtight and smoke-tight seal even with diagonally cut pipes. From pipe size M25, the membrane surfaces are divided by separating strips. These ensure a secure cable routing and prevent damage and cable tacking.
