More Height, More Options

FireRock fireplaces come with a standard 34.5” opening height (with the exception of the Rumford style.) The height extension kit can be used to increase the height of a firebox’s finished opening by almost nine inches.
This accessory is perfect for designs that call for an arched opening that would normally reduce the open area of the firebox.
