Notes:

  • Use 24 GA limits for aluminum service door.
  • GJ, SJ, and LJ operators not recommended for use on doors/grilles too large to be manually operated. (Use MG, H, or LH on doors requiring manual hoist chain.)
  • LH or LJ operators are limited to 10 complete cycles per hour.
  • This chart is intended as a guideline only. Doors and balance springs musts be in good operating condition and adjusted to manufacturers specifications.
  • The chart is based on door travel of approximately 2/3 foot per second. Doors traveling in excess of 2/3 foot per second will require increased HP rating or decreased maximum sq. ft. rating.
  • High cycle may require upgraded operator.
