1. Product Overview
The Greenlee 39265 Flexible Mandrel Cable Puller is designed for preparing 2-inch ducts prior to cable installation. Its primary function is to clear out minor obstructions such as mud, dirt, and light debris, ensuring a clean path for cables.
This mandrel features a flexible design with convex contacts between its polyurethane disks, allowing it to navigate tight bends within ducts. The tapered profile and pulling eyes on both ends enable bidirectional pulling. The polyurethane disks are engineered to prevent damage to the inner walls of the duct during operation.

2. Setup
- Inspect the Mandrel: Before each use, visually inspect the Greenlee 39265 mandrel for any signs of damage, wear, or defects. Ensure the pulling eyes are securely attached and the polyurethane disks are intact.
- Prepare the Duct: Ensure the duct intended for cable installation is accessible at both ends. Remove any large, visible debris that could obstruct the mandrel.
- Attach Pulling Line: Securely attach a suitable pulling line (e.g., rope, tape, or wire) to one of the pulling eyes on the mandrel. Ensure the connection is robust enough to withstand the anticipated pulling force.
- Insert into Duct: Carefully insert the mandrel into one end of the 2-inch duct.
3. Operating Instructions
- Initiate Pulling: From the opposite end of the duct, begin to pull the line attached to the mandrel. Apply steady and consistent force.
- Monitor Progress: Observe the mandrel's movement through the duct. The flexible design allows it to navigate bends effectively.
- Clear Obstacles: The mandrel is designed to clear mud, dirt, and light obstacles. If significant resistance is encountered, do not apply excessive force. Instead, attempt to pull the mandrel back slightly and then forward again to dislodge the obstruction.
- Bidirectional Use: Due to its tapered profile and pulling eyes on both ends, the mandrel can be pulled in either direction if needed. This can be useful for dislodging stubborn debris.
- Complete the Pull: Continue pulling until the mandrel emerges from the other end of the duct, indicating a clear path.
- Remove Mandrel: Detach the pulling line from the mandrel.
4. Maintenance
- Cleaning: After each use, clean the mandrel to remove any accumulated dirt, mud, or debris. Use a damp cloth and mild detergent if necessary. Rinse thoroughly and allow to air dry.
- Inspection: Regularly inspect the polyurethane disks for cuts, tears, or excessive wear. Check the integrity of the steel pulling eyes and their crimped connections.
- Storage: Store the mandrel in a clean, dry place, away from direct sunlight and extreme temperatures, to prolong its lifespan.
- Polyurethane Material: The polyurethane disks are designed not to damage the inner walls of the duct. Avoid using harsh chemicals or abrasive cleaners that could degrade the material.
5. Troubleshooting
- Mandrel Stuck in Duct:
- If the mandrel encounters significant resistance and stops moving, do not force it.
- Attempt to pull the mandrel back a short distance, then try pulling forward again with steady force.
- If the obstruction persists, try pulling from the opposite end of the duct if feasible, utilizing the bidirectional pulling eyes.
- For severe blockages, alternative duct clearing methods may be required. The mandrel is intended for light obstacles.
- Difficulty Navigating Bends:
- The flexible design is optimized for tight bends. Ensure the pulling force is applied smoothly and consistently.
- Verify that the duct size is indeed 2-inch, as an undersized duct could cause issues.
