8" DuraPlus 24" Square Ceiling Support Box

The 8" DuraPlus 24" Square Ceiling Support Box is a versatile and durable component designed to enhance the functionality and aesthetics of your chimney installation. This robust support box is engineered to work seamlessly with flat, vaulted, or cathedral ceilings, providing a reliable foundation for up to 40' of chimney pipe.

Triple-Wall Construction for Enhanced Performance

The Simpson DuraPlus all-fuel chimney system stands out for its innovative triple-wall construction, which not only ensures fire safety but also maximizes efficiency. This design maintains a cool exterior while creating hot drafts inside, boosting stove efficiency and creating a fire-safe environment. The system features two insulating layers: a ceramic blanket and air space, providing security and eliminating hot spots commonly found in other types of insulation.
  • Triple-wall construction: Stays cool on the outside, provides hot drafts on the inside.
  • Fire-safe: Protects both the chimney and the building from potential hazards.

Easy Installation and Safety

The DuraPlus components are designed for easy installation, offering a precision twist-lock connection that secures without the need for gaskets or sealants. This not only simplifies the installation process but also maintains the safety and efficiency of the chimney after installation. A minimum of 2" clearance to combustibles is maintained, ensuring long-lasting performance.
  • Easy installation: Precision twist-lock connection for a secure fit.
  • Safe and efficient: 2" minimum clearance to combustibles for long-term reliability.
Whether you're outfitting a wood stove, fireplace, furnace, or other appliances fueled by wood, oil, coal, or gas, the 8" DuraPlus 24" Square Ceiling Support Box is a reliable choice for a worry-free chimney system.
