This permanently elastic, cylindrical foam plug provides an effective solution for smoke sealing in sensitive areas exposed to dust, fibers, and moisture. When exposed to heat, the plug forms a protective insulation layer that meets the requirements of fire resistance class S 90. It is ideal for sealing cable penetrations in walls and ceilings and complies with the standards according to DIN 4102 Part 9. During installation, the technical specifications of the general building approval must be observed to ensure safety and functionality. The plug is designed for a maximum cable occupancy of 60% per construction opening, making it excellent for various applications in electrical installations.
