This vent top fits the RV line of MetalBest round Type B gas vent pipe and is made to work with approved gas appliances only. It is not rated for wood burning applications. HVAC technicians and installers trust this type of vent top to cap gas vent systems and keep them protected from the elements. The 7-inch measurement refers to the inside diameter of the pipe or fitting. The outside diameter of the RV pipe is approximately one-half inch larger than the stated size. The outer shell is constructed from 28-gauge galvanized steel, which resists rust and holds up well in outdoor conditions. The inner liner is aluminum, which handles the heat and condensation common in gas vent systems. The vent top helps prevent rain, snow, and debris from entering the vent stack. An external screen is built into the top to block most bird species from nesting inside the flue. Keeping birds and debris out protects the appliance and maintains proper draft. This component is a standard part of a Type B double-wall gas vent assembly. Type B venting is commonly used with natural gas and propane appliances such as furnaces, boilers, water heaters, and unit heaters. The RV MetalBest line from Selkirk is widely used in the trade for its consistent sizing, material quality, and broad compatibility with approved gas appliances. Installing the correct vent cap is a required part of any compliant gas vent system. The 107800 is also known by the model designation 7RV-RT.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFits 7-inch inside diameter Type B round gas vent pipe in the RV MetalBest line\u003c\/li\u003e\n\u003cli\u003eExternal screen blocks most bird species and helps keep debris out of the flue\u003c\/li\u003e\n\u003cli\u003e28-gauge galvanized steel outer shell with aluminum inner liner for durability and heat resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Selkirk 107800 RV Metalbest Top provides reliable weather and debris protection for 7-inch Type B gas vent systems in residential and light commercial applications.
