The Blacksmith Forge Grate Frame is the cast iron carrier frame that holds the four riddle bars inside the Blacksmith Forge stove. If the outer frame cracks, warps, or corrodes it needs to be replaced to keep the grate assembly stable and working correctly. This is a high grade cast iron replacement part direct from Blacksmith. ✅ Compatible with: Blacksmith Forge stove (boiler and non-boiler versions) 🔧 Specifications Material: Cast iron Heat resistance: 650°C Part type: Grate frame / carrier frame The grate frame holds the four riddle bars in position and channels ash downward into the ash pan. A damaged or misshapen frame will prevent the riddle bars from seating correctly, which reduces airflow and combustion efficiency. Clean and remove all inner parts carefully before fitting the replacement frame.
