Stove Hearth Saver to fit in your fireplace. Although stoves are a beautiful and comforting feature in any home, you have to be careful when loading and unloading fuel and ashes. Opening the door of a lit stove leaves your floor or carpet vulnerable to stray cinders which may fall out. Place it on the floor in front of your stove and it will catch the cinders and hot ash which can otherwise cause irreparable damage.
