摘要：<p>Fire-restraining barrier for the penetration of conduits through a wall opening (1), comprising an enclosure body (3) adapted to be inserted in the wall opening (1), the enclosure body (3) having at least one throughgoing receiving channel (5, 7) for receiving and enclosing at least one conduit and consists at least partly of a fire protection material which under the influence of a fire forms an obstacle against spreading of the fire, characterized in that the barrier comprises a fire-resistant grid (17) dimensioned to fill out the wall opening (1), in which grid throughgoing insertion channels (19, 21) are provided as mesh openings, in that the non-needed mesh openings (27) can be closed by fire-restraining covers (23, 25), and in that the grid (17) has a strength which is sufficient to receive a plurality of enclosure bodies (3) with conduits therein.</p>
