The PowerMaster J-54 Jackshaft Operator is a 1/2 HP, 230/460V, 3-phase heavy-duty commercial operator engineered for rolling steel doors, sectional overhead doors, grilles, and industrial barrier applications. Designed to deliver dependable, consistent torque and long service life, the J-54 offers the durability required for demanding commercial environments.
This versatile model supports dual-voltage operation (230V or 460V), making it suitable for facilities with varying electrical infrastructures. Its jackshaft configuration allows direct mounting to the door shaft, providing a compact solution in areas with limited overhead space. Built with industrial-grade components and designed for integration with modern safety and access control systems, the J-54 ensures reliable and precise daily operation.
