The Fasco FM55 Mounting Bracket Kit is a heavy-duty, 3-leg torsion-flex system engineered for 5.5-inch (5-5/8") diameter motors. As a professional-grade direct drive blower motor bracket, the FM55 is the designated replacement for the legacy Fasco 44 bracket, providing a more robust vibration isolation mount to mitigate harmonic noise and torsional stress within the air handler or furnace housing. This versatile HVAC motor mounting kit accommodates 48-frame motors and features dual bolt circle patterns at 9 inches and 10.18 inches, ensuring precise alignment and stability in high-static pressure applications. Unlike generic alternatives, this Fasco motor mount clamps directly to the motor shell, requiring no complex preassembly and facilitating rapid field replacement for contractors. By utilizing a flex mount bracket design, it effectively isolates the motor from the blower wheel assembly, extending the service life of critical system components. Key Benefits for HVAC Contractors Universal Compatibility: Engineered specifically for 5.5-inch diameter motors with 9" and 10.18" bolt circles. Direct Replacement: Designed as the official upgrade path for the Fasco 44 series, ensuring a perfect fit without housing modifications. Enhanced Vibration Control: Includes high-durometer grommets and eyelets to eliminate resonant noise in residential and commercial blowers. Simplified Installation: The clamp-to-shell design allows for quick securing of the motor, reducing labor time during emergency service calls. Regulatory Compliance: Fully UL Recognized and CSA Certified to meet stringent safety standards for HVACR equipment. Common Installation Questions Does this kit include the mounting hardware? Yes, the FM55 kit comes complete with three grommets, one mounting bolt, one locking nut, and three steel washers required for a standard 3-leg installation. Is the FM55 compatible with a 4-leg setup? The FM55 is a 3-leg torsion bracket. For applications requiring a 4-leg configuration, you should specify the FM554A model. Will this bracket fit a motor with a 5-inch diameter? No, this kit is specifically sized for 5.5-inch (5-5/8") diameter motors. For 5-inch motors, the FM50 mounting kit is the appropriate technical selection. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
