Harman SF-250 Ceramic Glass Panel (8 1/2" x 4 1/2") is the correct OEM-style replacement when your stove’s view window is cracked, cloudy, or unsafe. Made from high-temperature pyro-ceramic glass, this panel is engineered specifically for wood stove use and rated to withstand up to 1,400°F (760°C). It restores a clear, beautiful view of your fire while maintaining the safety and efficiency your Harman stove was designed for. This is not tempered glass—it’s real ceramic glass for wood stoves, built to handle extreme heat without warping or shattering.
Precision-cut for an exact fit, this Harman replacement glass is compatible with Harman Triple Frame, Magnafire Elite, Mark II, Mark III, SF-150, and SF-250 wood stoves. Proudly made in the USA, it offers long-term durability, minimal thermal expansion, and dependable performance season after season. Pair it with a fresh gasket (sold separately), and your stove is back to delivering safe heat and a crystal-clear flame view—no guessing, no shortcuts, no compromises.
