Product Features & Fitment

This motor features a patent-pending multi-mount, repositionable bolt-on base and C-face, allowing rapid reconfiguration of the conduit box and mounting position without the need for additional parts. The fan guard is rotatable in 90° increments to align with the base when repositioned for F-2 or F-3 conduit box locations. The conduit box itself rotates 180° for 360° conduit entry, with 7/8” and 1-1/8” knockouts on all sides and a gasket to maintain an IP44 or better enclosure rating.

The combination base includes holes and slots compatible with NEMA 56, 56H, 143T, and 145T mounting patterns and can be rotated to F-2 or F-3 conduit box locations. Cast-in end frame markings indicate base locations for F-1, F-2, and F-3 conduit box positions, and mounting screws allow secure repositioning. This design ensures compatibility with standard 56 frame motors, providing an easy, low-cost replacement option with multiple mounting configurations.
