The Charnwood Country 4 baffle/Throatplate Mk 1 and 2 is a high quality genuine steel plate that sits at the roof of the stove and provides protection to the roof of the stove to avoid damage to the flue.  The Country 4 baffle plate slows down the flames within the stove to ensure more heat stays within the fire box before any heat travels up the chimney and ensures high efficiency.
