• The system’s snap-in/snap-out clip design is widely praised for enabling fast setup and repositioning without disturbing existing cable layouts.
• Technicians value the compatibility with standard I-beam and C-channel cable trays, making it highly versatile across commercial and industrial job sites.
• The 12-pack configuration is considered cost-efficient for large-scale installations, reducing downtime by allowing multiple roller points along long tray runs.
• Overall, professionals see this as a durable, jobsite-ready accessory that improves pulling efficiency, safety, and cable management consistency, especially in heavy electrical infrastructure work.

Q: What is the Greenlee 31931 Haines Cable Tray Roller used for?
A: It is used to support and guide electrical cable during installation in cable trays, reducing friction and preventing cable damage during pulls.

Q: What does this 12-pack include?
A: It includes 12 high-impact ABS plastic Haines rollers designed for use with Greenlee cable tray pulling systems.

Q: What size are the rollers?
A: Each roller is approximately 6 in (152 mm) diameter x 7 in width, suitable for standard cable tray applications.

Q: What materials are the rollers made from?
A: They are made from high-impact ABS plastic, designed for durability and low friction during cable pulls.

Q: What systems are these rollers compatible with?
A: They are designed for use with Greenlee’s 1-1/2 in steel conduit spindle system and mounting clips (e.g., 31930/31927 components).

Q: How do they mount in cable trays?
A: They snap into mounting clips that attach to I-beam and C-channel cable trays without disturbing existing cable.

Q: What does “new surplus” mean?
A: It means the rollers are unused excess inventory, typically in new or like-new condition, often repackaged but fully functional.

Q: What is the main benefit of using these rollers?
A: They reduce cable drag, improve pull safety, and help prevent insulation damage during long or complex cable tray installations.

• Clean rollers after each use: Remove dust, metal shavings, and cable residue to maintain smooth cable movement.
• Inspect ABS rollers & clips: Check for cracks, wear, or deformation in high-impact plastic components before setup.
• Lubricate spindle points: Apply light cable-rated lubricant (e.g., Greenlee Cable-Cream) to reduce friction and wear.
• Check mounting clips: Ensure I-beam and C-channel tray clips are tight, aligned, and not bent before load.
• Verify free roller rotation: Rollers should spin smoothly without resistance or wobble—replace if binding occurs.
• Avoid overloading sections: Distribute cable weight evenly across rollers to prevent deformation or sagging.
• Keep alignment straight: Misalignment increases friction and can damage both cable jacket and rollers.
• Store dry & protected: Prevent UV exposure and moisture buildup to extend life of ABS components.
• Batch inspection (12-pack): Rotate and inspect all units before field use to ensure consistent performance across sets.
• Replace worn clips early: Clips are a high-stress point and should be replaced at first sign of fatigue.
