Adjustable Latch Action:

  • The last 15 degrees of the closing cycle is known as the latch action (or snap action), it's designed to help give a door closer a little extra force to help it overcome any door seals, or latches that might prevent the door from closing within the frame.
  • The latch action can be adjusted by turning a screw in the body of the closer.
  • By turning the latch action off or very low the door closer will softly close into the frame, by turning the latch action to it's maximum setting the door closer will push into the door frame with extra force.
