Blaze King Wood Stove Replacement door handle kit (New Style). The block on the door handle grabs the latch on the unit allowing the door to seal tightly against the body of the stove. If the door is not sealing tightly, it can cause a decrease in efficiency, inability to control the burn rate and may allow smoke/flue gasses to enter the room.
*This is for newer stoves with a single door handle. *
