This is a high grade cast iron Carrier Frame or Outer Grate Frame to suit the Hi-Flame Alpha 3 Non Boiler Stove. The Stove needs to be cleaned and all inner parts carefully removed to replace this part.
Please note that the Boiler version of the Alpha 3 Stove (AL910B) uses a different carrier frame and inner grate to the Alpha 3 Non Boiler due to the riddling function on the boiler version.
