Modular sealing blocks, such as those used in the Roxtec and DG/MCT Packing Systems, allow rapid installation by using removable layers to fit cables of varying diameters. Installers simply peel off layers until the block fits snugly around the cable, eliminating the need for custom cutting or complex adjustments . These systems are reusable, enabling easy addition or removal of cables without dismantling the entire seal .
SLIPSIL sealing plugs and similar self-compression designs provide a fast, bolt-free solution for single or multiple cable penetrations. These plugs automatically compress to fill gaps, offering fire, water, and gas tightness without periodic re-tightening . They are particularly useful in industrial or marine environments where speed and reliability are critical.
For fire-rated installations, quick sealing can be achieved using firestop packs, firestop mastic, or mineral wool in combination with backing plates. Properly installed, these materials ensure tight, crack-free seals around cable trays and conduits, with gaps kept below 1 cm² and packing thicknesses of at least 24 cm . Pre-cut or modular firestop components can significantly reduce installation time while maintaining compliance with fire safety standards.
