Imperial KK0156 Fire Brick 9x4.5x1.25 in Fireplace Replacement

Product Description

The IMPERIAL MFG GROUP USA INC KK0156 is a standard-size fire brick designed for refractory applications in residential fireplace fireboxes. Each brick measures 9 inches long by 4.5 inches wide by 1.25 inches thick and is rated for continuous service temperatures up to 2,200 degrees F. These bricks are used to rebuild or repair the inner lining of a firebox, replacing old, cracked, or spalled refractory material that has degraded from repeated heat cycling. Installation is typically performed by fireplace technicians, masons, or qualified contractors working on solid-fuel or gas appliance enclosures.

This fire brick is suited for firebox lining replacement in residential masonry and zero-clearance fireplace applications. It is sold in a package of 6 bricks, making it practical for full or partial firebox rebuilds. The 1.25-inch thickness profile fits standard firebox wall dimensions common in production and custom-built fireplace systems. Contractors and service technicians use these bricks to restore the structural and thermal integrity of a firebox that has sustained heat damage or physical deterioration over time.
