7 Inch x 11 Inch DuraPlus Square Ceiling Support Box

The elegant black appearance matches its entirely functional design. The innovative triple-wall construction increases stove efficiency by keeping things warm within while keeping things cool outside. As a result, the building and chimney are both protected by a fire-safe framework. There are two layers of insulation in the triple-wall chimney. An air gap and ceramic blanket offer security. By being securely kept in place, the ceramic blanket insulation minimizes hot spots that are common with loose-fill varieties of insulation.
