Greenlee Poly Braid Rope 1/2 x 300

Description

Pull high-tension underground power conductors using the Greenlee 455 Poly Braid Rope through long commercial conduit runs. Dual-braided synthetic polyester construction withstands high capstan friction without line melting during 4,000 lbs pulling cycles. The low stretch characteristics require steady operator monitoring at the puller capstan to prevent abrupt line snapback under high mechanical line loads.

High-tenacity polyester fibers form a double-braided jacket over an internal synthetic core, measuring 1/2in diameter across a 300ft continuous length. Total spool weight reaches 27 lbs. The rope architecture yields a verified 4,000 lbs average breaking strength with an 800 lbs safe working load limit. The moisture-resistant outer jacket resists motor oil, transformer fluid, and ground chemicals from minus 20°F to 140°F.

Key Features of Greenlee 455

Utility electrical contractors and substation maintenance crews buy Greenlee 455 rope spools to feed heavy cables. Jobsite purchasing directors choose this factory-spliced pulling line for dependable tensile endurance that prevents snapped lines inside underground duct banks.

• Double-braided polyester jacket distributes tensile stress evenly across the inner load-bearing synthetic core.
• High-tenacity synthetic fibers resist internal heat friction during continuous pulling around high-speed capstan drums.
• Low stretch profile delivers predictable cable movement through complex conduit bends without elastic recoil.
• Factory-spliced pulling eye on the rope terminal allows direct connection to pulling swivels and cable grips.
• Outer braid resists external abrasion against rough PVC, aluminum, and rigid galvanized steel conduit burrs.
• Rot-proof synthetic construction prevents mildew breakdown when wet lines store on spools inside service vans.
• Continuous 300ft line length covers long conduit runs without requiring dangerous intermediate line knots.
• Clean outer fiber finish reduces capstan drum wear to maintain consistent line grip during heavy operations.

Tensile Load Stretch Bench Verification

Static proof load testing subjects the line to 1,200 lbs working tension, recording minimal 4.8 percent elongation across the full 300ft span. Thermal sensors verify zero jacket softening during 15-minute continuous capstan friction pulls at 40 FPM under load. Outer sheath distortion measures zero inches along the entire line after load release. Sound meters record 54 dB spool payout noise.

Conduit Pulling Usability Negative Filter

Do not use this synthetic pulling line for dynamic overhead personal fall arrest or crane hoisting. Never exceed the 800 lbs safe working load limit when pulling through sharp unreamed conduit edges. Riggers wearing heavy split-cowhide gloves maintain positive friction grip on the line during capstan wrapping.

• Inspect outer rope jacket for broken strands or friction burns before every major wire pull.
• Rinse abrasive trench grit from the line using clean water after wet mud conduit pulls.
• Store dry rope spools off concrete floors inside covered utility trailers away from sunlight.

Factory Warranty Terms Spool Manifest

Greenlee warrants this pulling line with a 1-Year limited warranty against material and manufacturing defects. The factory shipping package contains the 300ft spool of Greenlee 455 1/2in double braid rope, factory-spliced terminal eye, protective plastic storage wrap, and technical load chart.
