Yoke frame slides into the end of conduit and holds sheave, allowing the cable being fed into the conduit to smoothly roll over the sheave.

5" (127 mm) wide aluminum alloy sheave with self-lubricating bearings.

Split tube for easy removal after cable is installed

For 3-Inch Conduit

10 x 10 x 12 inches

What Our Experts Think
  • Heavy-duty cable feeding sheave designed for 3" conduit, ensuring smooth and controlled cable entry during pulling operations
  • Built-in aluminum alloy sheave (5" wide) with self-lubricating bearings for low-friction performance and reduced cable wear
  • Engineered yoke frame design slides directly into conduit ends, improving alignment and stability during installation
  • Split-tube construction allows fast removal after cable pulling, saving valuable jobsite time
  • Supports high pulling loads up to 6,050 lb (at 15° angle), making it suitable for demanding commercial electrical runs
  • Helps prevent cable damage and binding, improving efficiency and reducing rework during long conduit pulls
  • Durable Greenlee professional-grade build quality, trusted by electrical contractors for reliable field performance
  • Ideal for use in industrial, commercial, and infrastructure conduit installations where controlled cable feeding is critical
Q&A

Q: What is the Greenlee 441-3 Feeding Sheave used for?
A: It is used to guide and reduce friction when pulling electrical cable into 3-inch conduit, improving cable flow and preventing jacket damage.

Q: What conduit size is it designed for?
A: It is specifically designed for 3 in. conduit systems, fitting securely at the conduit entry point during cable installation.

Q: How does the feeding sheave work?
A: A yoke frame slides into the conduit end, holding a rotating aluminum sheave that allows cable to roll smoothly into the conduit.

Q: What materials is it made from?
A: It features a 5 in. wide aluminum alloy sheave with self-lubricating bearings for durability and low friction operation.

Q: What is the benefit of using this tool?
A: It helps reduce cable drag, prevent insulation wear, and improve safety and efficiency during cable pulling operations.

Q: Can it be removed after use?
A: Yes, it includes a split-tube design for quick removal after the cable pull is complete.

Q: What type of job sites is it used on?
A: It is commonly used in commercial, industrial, and utility electrical installations involving conduit cable pulls.

Q: Is it reusable?
A: Yes, it is a durable, reusable cable pulling accessory designed for repeated jobsite use.

Maintenance Tips
  • Clean sheave groove regularly: Remove dirt, cable residue, and metal particles to maintain smooth cable feeding.
  • Inspect sheave wheel: Check for cracks, flat spots, or groove wear that could damage cable jackets.
  • Lubricate bearings: Apply light grease to the axle/bearing area for smooth rotation and reduced friction.
  • Check frame alignment: Ensure sheave is properly aligned with the cable path to prevent side loading.
  • Verify free rotation: The wheel should spin freely without wobble or resistance before each use.
  • Inspect mounting hardware: Tighten shackles, pins, or clamps to avoid movement during pulling operations.
  • Avoid overload angles: Do not exceed rated cable bend radius to prevent cable and sheave damage.
  • Watch for rope/cable wear marks: Early signs of abrasion indicate misalignment or worn groove surfaces.
  • Protect from corrosion: Store dry and clean, especially after use in wet or outdoor environments.
  • Routine safety check: Perform quick pre-use inspection before every pull setup for safe operation.
