8 Inch x 24 Inch DuraPlus Square Ceiling Support Box

The Square Ceiling Support Box has a sophisticated black exterior that complements its totally practical design. Stove efficiency is increased by the novel triple wall structure, which keeps things warm while keeping things cool outside. As a result, a fire-safe framework shields the building and chimney from damage. The triple-wall chimney is insulated in two layers. Security is provided via an air gap and a ceramic blanket.
