Nelson Firestop Bricks are easy to install, easy to position, and ideal for applications where there might be a need to re-penetrate an area. When a brick comes into contact with fire, the brick material expands within the opening, forming a solid char that prevents through-penetration of the fire for up to 2 hours. Because of its versatility, this economical, durable, labor-saving firestop material is ideal for cable or cable tray penetrations.
