Step-By-Step Guide To Adjusting LCN Door Closers

  • Preparing For Adjustment

Before diving into adjustment, familiarize yourself with the door closer's components. Safety is paramount, so ensure the door is secured to prevent accidents during the adjustment process.

Identifying the adjustment screws and valves is crucial. Typically, there are separate valves for adjusting closing speed, latching speed, and backcheck. Knowing their locations sets the stage for precise adjustments.

  • Adjusting Closing Speed

Closing speed adjustment influences how quickly the door closes after being opened. This adjustment prevents the door from slamming or closing too slowly. Using the appropriate valve, gradually turn it clockwise to increase the closing speed or counterclockwise to decrease it. Regular testing helps find the right balance.

  • Adjusting Latching Speed And Backcheck

Latching speed controls the final part of the door's closing cycle. Ensuring it securely latches without causing undue strain. Backcheck controls the resistance the door experiences when opened forcefully.

To adjust these settings, locate the relevant screws or valves and follow the manufacturer's instructions. Finding the right equilibrium between latching speed and checking ensures optimal door movement.

  • Checking And Testing

After adjustments, complete testing is necessary. Open and close the door multiple times, observing its behaviour. The door should close smoothly, latch securely, and not exhibit any irregular movements. If adjustments don't yield the desired results, revisit the process and fine-tune as needed.

  • Using The LCN Door Closers Instructions

While this guide provides a practical approach to adjustment, referring to the manufacturer's instructions is equally important. Each door closer model may have unique features and requirements. Combining the practical steps outlined here with the manufacturer's guidance ensures accuracy and precision.


In adjusting LCN door closers, you empower yourself to maintain safe and controlled door movement.
