Selkirk 206430 Wall Support Kit Type Ht Class a Double Wall Stainless Steel 6 Inch

Product Description

The Selkirk 206430 is a Type HT Wall Support Kit designed for use with Class A double wall chimney pipe systems. This kit provides a secure mounting point for chimney runs where a lateral connection meets the vertical chimney stack, whether the installation is located on the interior or exterior of the structure. HVAC technicians and chimney installers rely on this type of wall support to anchor and stabilize long vertical chimney runs while maintaining proper clearances from combustible wall surfaces. The Selkirk 206430 is built from stainless steel with a galvanized finish, giving it resistance to the high heat and corrosive byproducts common in chimney exhaust applications. This wall support kit is specifically engineered for use with an Insulated Tee, making it suitable for installations where the flue system transitions from a horizontal connector to a vertical chimney. For 5, 6, 7, and 8 inch diameter sizes, the wall support is rated to carry up to 60 feet of chimney height at a standoff of 2 inches from the wall surface. For larger sizes, including 10, 12, and 14 inch diameters, the rated capacity is 40 feet of chimney height. This 6 inch diameter unit measures 6 inches in diameter, 10 and 5 eighths inches wide, and 18 and 7 eighths inches in height, making it compatible with standard residential and light commercial chimney configurations. The Type HT designation indicates it has been tested for use in fully enclosed chimney chases, which is a critical specification for code-compliant installations in new construction and retrofit projects. Installers working with wood-burning appliances, fireplaces, gas appliances, or oil-fired heating equipment requiring Class A venting will find this wall support kit meets the structural demands of the job.
