Item # 9W78SWUPC: 662492008058
7/12-13/12 SQUARE CEILING SUPPORT BOX

This Support Box DuraPlus is designed to stay cool on the outside, to provide a hot draft on the inside, to boost stove efficiency, and to provide for a fire-safe design that protects both the chimney and the building.

This triple-wall chimney features two insulating layers (ceramic blanket, plus air space). The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations.

In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction. DuraPlus Chimney is a triple-wall, all-fuel chimney for use with wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas.

  • DuraPlus all-fuel - use with flat, vaulted or cathedral ceilings
  • 24" tall support box
  • For 7/12-13/12 ceiling pitch
  • Supports up to 35 ft. of DuraPlus Chimney
  • Starter section built in
