MB55 – BRACKET (3 ARM FLEXIBLE)

If your indoor unit runs but produces weak or no airflow, the blower motor may need replacement. This 3-arm flexible bracket mounts 5.5″ diameter direct-drive blower motors and absorbs vibration to keep things quiet. Flexible arms reduce the buzzing and humming that rigid brackets sometimes transmit.

Specs: 3-arm flexible design, fits 5.5″ diameter motors, up to 1/2 HP, includes mounting hardware

Replaces: FM55, MB55, TFM556 — Supco brand

Fits: Furnaces and air handlers using 5.5″ diameter direct-drive blower motors from Goodman, Rheem, Trane, Carrier, Lennox, York, and others.
