Square ready-to-finish fire pit enclosures that are made from Hardiebacker fiber cement board and G90 marine-grade galvanized steel framing. The enclosure can be finished on-site to match the surrounding landscape or exterior design, using materials such as granite, stone, stucco, or Supercast Concrete tops. It saves time on the project while still allowing customization of the appearance. A UL Listed Crystal Fire Plus Burner can be chosen separately to complete the look.
