Selkirk 105400 5 Inch Rv Support Assembly 5RV-GVS

Product Description

The Selkirk 105400 is a 5 inch RV Support Assembly designed for use with MetalBest Round Type B gas vent systems. 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.

The 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.

This 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.

The 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.
