5. Setup and Installation
Follow these steps for proper installation of the ECENCE Roller Shutter Buffer Stoppers:
- Identify Mounting Location: The stoppers are typically mounted on the bottom-most slat of the roller shutter curtain or on the lower roller shutter profile. Ensure the location allows the shutter to fully close while preventing it from retracting too far into the box.
- Mark Drill Points: Hold the stopper against the desired mounting point and mark the center for drilling. Ensure the stopper is positioned symmetrically and at an appropriate distance from the edges of the shutter. For two stoppers per shutter, place them equidistant from the center.
- Drill Pilot Holes: Using an appropriate drill bit for your shutter material (e.g., aluminum, PVC), drill pilot holes at the marked points. The hole should be slightly smaller than the screw diameter to ensure a secure fit.
- Attach Stopper: Place the washer onto the screw, then insert the screw through the center of the buffer stopper. Align the screw with the pilot hole and carefully screw the stopper into place. Do not overtighten, as this may damage the shutter material or the stopper.
- Repeat for all Shutters: Install stoppers on all roller shutters as needed.
- Test Functionality: After installation, operate the roller shutter to ensure the stoppers effectively prevent the curtain from being pulled too far up, while allowing full closure.

6. Operating Principle
The ECENCE Roller Shutter Buffer Stoppers function as a physical barrier. When the roller shutter is raised, the stoppers make contact with the bottom edge of the shutter box or window frame, preventing the shutter curtain from being pulled completely inside. This protects the shutter mechanism from over-winding and ensures the shutter remains accessible for manual operation (e.g., via strap or crank).

7. Maintenance
The ECENCE Roller Shutter Buffer Stoppers require minimal maintenance due to their durable and weather-resistant construction. However, regular inspection is recommended:
- Cleaning: Periodically wipe the stoppers with a damp cloth to remove dust and dirt. Avoid abrasive cleaners.
- Inspection: Annually check the stoppers for any signs of wear, cracking, or damage, especially after extreme weather conditions. Ensure they are still securely fastened.
- Replacement: If a stopper shows significant wear or damage, replace it promptly to maintain the protective function of your roller shutter.

8. Troubleshooting
Most issues related to the buffer stoppers are minor and can be resolved easily:
| Problem | Possible Cause | Solution |
|---|---|---|
| Shutter still retracts too far. | Stoppers are not installed correctly or are damaged. | Check installation. Ensure stoppers are securely fastened and positioned correctly. Replace if damaged. |
| Stoppers are loose. | Screws are not tight enough or have come loose. | Tighten the screws. If the hole is stripped, consider relocating the stopper slightly or using a larger screw (with caution). |
| Stoppers are discolored or brittle. | Prolonged exposure to harsh weather or age. | This is normal wear over time. Replace the stoppers to ensure continued protection. |
