The Blacksmith Forge Grate Bars are a set of four cast iron riddle bars for the Blacksmith Forge wood burning stove. Grate bars gradually warp and burn through with extended use, reducing airflow efficiency and making riddling difficult. Replacing worn bars restores proper combustion control and extends the life of the stove. ✅ Compatible with: Blacksmith Forge stove (boiler and non-boiler versions) 🔧 Specifications Quantity: Set of 4 riddle bars Material: Cast iron Heat resistance: 650°C Part type: Grate bars / riddling bars The grate bars sit inside the carrier frame and allow ash to fall through into the ash pan while supporting the fire bed. When bars burn through or warp severely they should be replaced to maintain safe and efficient operation. To fit, remove the fire fence and lift out the existing bars before disconnecting the riddle arm.
