Power Adjustment Via Spring:

Separate power adjustment, by means of an allen key at the end of the closer body, this closer can be adjusted to suit door widths from 850mm to 1250mm EN power size 2-5

4	1100mm	80kg
5	1250mm	100kg

Adjustable Closing Speed:

The closing speed can be adjusted by turning a small screw in the body of the closer.

By turning the screw in the body the rate at which oil flows through the closer changes in turn controlling how fast the closer will shut the door.

Speed adjustment can be controlled from approximately the first 180 degrees down to the last 15 degrees of the closing cycle.

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.

Adjustable Backcheck:

This function slows and or stops the door during it's opening cycle, so that it cannot be flung open violently and damage any adjacent walls.

Backcheck function can be adjusted by turning a small screw in the body of the closer.
