Installation Instructions
These cable stops are designed for simple installation to secure or terminate cables. Follow these general steps:
- Prepare the Cable: Ensure the cable end is clean and free of fraying. If necessary, trim the cable to the desired length.
- Insert Cable: Thread the end of the cable through the small hole in the cylindrical body of the cable stop.
- Position the Cable Stop: Slide the cable stop along the cable to the desired position where it needs to be anchored or terminated.
- Tighten the Screw: Use an appropriate tool to tighten the screw terminal on the side of the cable stop. Ensure the screw is tightened firmly to compress the cable and prevent it from slipping. Do not overtighten, as this could damage the cable.
- Verify Security: Gently pull on the cable to confirm that the cable stop is securely fastened and does not move.

Maintenance
Dorman 03339 Cable Stops require minimal maintenance due to their durable brass construction. However, periodic inspection is recommended:
- Visual Inspection: Regularly check the cable stop and the cable for any signs of wear, corrosion, or damage.
- Tightness Check: Ensure the screw terminal remains tight and the cable stop is not loose on the cable. Re-tighten if necessary.
- Cleaning: If used in harsh environments, clean the cable stop with a damp cloth to remove dirt or debris. Avoid abrasive cleaners.
Troubleshooting
If you encounter issues with your Dorman 03339 Cable Stops, consider the following:
- Cable Slippage: If the cable slips through the stop, ensure the screw terminal is adequately tightened. Verify that the cable diameter is 1/8 inch; using an incorrect cable size may lead to slippage.
- Difficulty Tightening: Check for any debris or damage to the screw threads or the cable stop body. Ensure you are using the correct tool for tightening.
- Corrosion: While made of brass for rust prevention, extreme conditions can still cause degradation. If significant corrosion occurs, replacement may be necessary.
