What Is it?
7B26A309 is an OEM right-side refractory firebrick designed specifically for Security BIS 1.2 zero-clearance wood-burning fireplaces manufactured under the Security Chimneys and IHP (Innovative Hearth Products) brand umbrella. Cast from heavy-duty, high-density refractory ceramic with an authentic stacked brick pattern, it lines the right interior chamber wall to insulate the exterior firebox steel from severe combustion temperatures. By storing and radiating intense thermal energy back into the firebox, it maintains the extreme heat required for clean, efficient secondary combustion while radiating heat into the living space. If your original right refractory panel is cracked, chipped, or missing chunks from heavy log impacts, installing this genuine factory replacement brick restores proper thermal efficiency, code compliance, and structural firebox protection.
