Rated to 180 pounds load capacity and 150 psi pressure, this flange is built for mechanical and HVAC pipe support applications where reliable overhead attachment is required. The plain iron finish suits standard interior environments. At 2.62 inches overall length and a 1-3\/4-inch hole center-to-center spacing, it mounts with 12 screws for a stable, multi-point connection. Licensed pipefitters, plumbers, and HVAC mechanics install this type of hardware during new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis ceiling flange is suited for residential and light commercial piping systems where overhead pipe support or hanger rod termination is required. It threads directly onto 1\/2-inch iron pipe or accepts a 1\/2-inch hanger rod, making it a practical solution for suspending duct hangers, conduit supports, and similar mechanical systems from concrete, wood joist, or steel ceiling structures. It is commonly used in HVAC, plumbing, and general mechanical rough-in work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e180-pound rated load capacity for dependable overhead pipe and rod support\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for standard piping system applications\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction provides strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eThreaded 1\/2-inch connection accepts standard iron pipe or hanger rod\u003c\/li\u003e\n  \u003cli\u003e12-screw mounting pattern with 1-3\/4-inch hole center-to-center for secure attachment\u003c\/li\u003e\n  \u003cli\u003ePlain finish for use in standard interior mechanical spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting compatible with standard 1\/2-inch threaded iron pipe and 1\/2-inch hanger rod systems used in residential and commercial HVAC, plumbing, and mechanical piping support applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, pipefitter, or HVAC mechanic. Shut off any pressurized systems in the work area before attaching or removing pipe support hardware. Ensure the mounting surface can support the full rated load before fastening.
