 New & Improved Erie AG/AH 2-Position PopTop™ Actuators
Erie AG/AH 2-Position PopTop Actuators have been upgraded!  Invensys has redesigned and upgraded the patented Erie PopTopTM actuator series. They have incorporated your ideas and listened to your feedback, and now the 2-Position PopTop fits in baseboard applications!


  • Pricing remains the same!
  • All part numbers remain the same!
  • The new actuators are a direct replacement for all existing Erie 2-Position PopTop Actuators!

AG and AH 2-Position PopTop Actuator’s Improvements Include:

AG Series

  • Narrower dimensions: The new General Close-off (AG) Actuators are 2 3/8" wide (¼" narrower than the previous actuator footprint). This new design will now allow for easy installation in baseboard heating units.
  • Manual release button moved: The release button has been moved to the end of the actuator for better accessibility.
  • Improved Close-off ratings: The close-off pressures have been increased by up to 10%.
  • UL listed: Actuators have been upgraded from UL-429 recognized to UL-873 listed.

AH Series

  • Narrower dimensions: The new High Close-off (AH) Actuators now use the previous AG Actuator platform. This reduces the width of the AH actuator 3/8".
  • Manual override: The AH now utilizes the same design as the AG.
  • UL listed: Actuators have been upgraded from UL-429 recognized to UL-873 listed.
  • We will be transitioning to the new product over the next 30 days. For easy recognition, the new product will have a star on both the box and label. The actuator dimensions are smaller, but have no fear; they are a direct replacement to the previous Erie PopTop Two-Position Actuators.
