Height Extension Kit
With the exception of Rumford, FireRock units come standard with a 34.5″ opening height. FireRock’s Height Extension Kit can be used to increase the 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.
A Height Extension Kit is a three-piece unit that sets on the baseplace and raises the opening height by 8-5/8".
- This accessory may not be used with LiteRock or See-Through models.
- Treat as another layer of block at installation.
Important: Please consult local building codes for specifics regarding any masonry fireplace application.
