The collar fits around the outside of the vent pipe and anchors to framing or structural members, maintaining proper pipe alignment throughout the vent run. It is used in Category I gas appliance venting systems, including those serving gas furnaces, boilers, and water heaters that exhaust at low positive pressure. Licensed HVAC technicians and plumbers install this component during new construction and replacement vent system projects.\u003c\/p\u003e\n\u003cp\u003eThis support collar is intended for use in residential and light commercial vertical B-vent installations where code requires the vent pipe to be secured at designated intervals. The 04PC is designed to work within 4-inch double-wall B-vent systems, holding the pipe in position against framing, floor joists, or structural blocking. Proper installation at required support intervals helps prevent pipe sag, joint separation, and misalignment over the life of the venting system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 4-inch B-vent pipe, providing a secure fit around standard double-wall vent pipe\u003c\/li\u003e\n  \u003cli\u003eAnchors to framing or structural support members to maintain vertical pipe alignment\u003c\/li\u003e\n  \u003cli\u003eSuitable for Category I gas appliance venting applications\u003c\/li\u003e\n  \u003cli\u003eSupports proper vent system integrity by stabilizing the pipe at required mounting points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style support collar for use with 4-inch double-wall B-vent pipe systems in Category I gas appliance venting installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with the National Fuel Gas Code (NFPA 54) and applicable local codes.
