This support assembly is a key component in properly securing and protecting gas vent pipe installations in residential, light commercial, and industrial settings. HVAC technicians and installers rely on this type of hardware to keep vent pipe runs stable, code-compliant, and safe throughout the life of the system.\u003c\/p\u003e\u003cp\u003eThe support plate included with the 105400 assembly is designed to be installed above the joist. This positioning keeps the vent pipe firmly in place while also serving a critical secondary function: acting as a firestop. A firestop barrier helps prevent the spread of fire and combustion gases between floor levels or structural cavities, which is an important code requirement in many jurisdictions. This dual-purpose design reduces the need for additional firestop materials in qualifying installations.\u003c\/p\u003e\u003cp\u003eThis assembly is rated to support a maximum of 60 feet of gas vent run, making it suitable for multi-story applications or longer vertical vent paths. The 5 inch size refers to the inside diameter of the vent pipe. The outside diameter of the RV series pipe is approximately 0.5 inches larger than the stated size, which is standard for this product line and important to keep in mind when planning rough-in dimensions or wall clearances.\u003c\/p\u003e\u003cp\u003eThe outer shell of the RV series is constructed from 28 gauge galvanized steel, which provides corrosion resistance and structural durability. The inner liner is aluminum, a material well suited for handling the temperatures and moisture present in gas appliance exhaust. Together, these materials meet the demands of Type B gas venting applications where double-wall construction is required. This product is compatible with approved gas appliances and is part of the broader Selkirk MetalBest RV line of round gas vent pipe and fittings.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSupport plate installs above the joist and doubles as a firestop for code-compliant installations\u003c\/li\u003e\n\u003cli\u003eRated to support up to 60 feet of Type B gas vent pipe\u003c\/li\u003e\n\u003cli\u003eOuter shell is 28 gauge galvanized steel with an aluminum inner liner for durability and heat resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Selkirk 105400 RV Support Assembly provides structural support and firestop protection for 5 inch Type B gas vent systems in residential and light commercial applications.
