ZIPEAK 5/16" (8mm) Galvanized Steel Zipline Cable (7,000 lbs)
"Upgraded our camp's 250ft line to this 5/16" ZIPEAK cable. The 7x19 weave flexes smoothly through pulleys without kinking, and the galvanization is holding up flawlessly in coastal humidity." — Verified Adventure Park Operator (★★★★★ 4.9/5 from 28 reviews)

Engineered for high-tension backyard spans and commercial adventure courses, the ZIPEAK 5/16" (8mm) Galvanized Steel Zipline Cable delivers industrial-strength safety and all-weather resilience. Crafted from high-tensile carbon steel strands in a flexible 7×19 aircraft-grade configuration, this wire rope provides an independently verified minimum breaking strength of 7,000 lbs (31.1 kN). Each outer wire is hot-dip galvanized to form an impenetrable barrier against rust, salt spray, acid rain, and UV degradation—ensuring smooth, friction-free trolley glides for years of continuous riding.
🛡️ Industrial Engineering & Durability Features
- 7,000 lbs (3,175 kg) Minimum Breaking Strength: Tested to withstand severe dynamic shock loads, high-speed braking forces, and tension surges from adult riders.
- Flexible 7×19 Aircraft Construction: Composed of 7 primary strands, each tightly wound with 19 individual steel wires. This design balances structural stiffness against cable sag while maintaining the flexibility required for smooth trolley pulley tracking.
- Deep Hot-Dip Galvanization: Thick zinc coating seals the steel core against oxidation and coastal humidity, preventing surface corrosion and wire embrittlement.
- Low Stretch & Fatigue Resistance: Pre-formed to minimize structural stretch over time, significantly reducing the need for repetitive retensioning after initial rigging.
- Universal Hardware Compatibility: Standard 5/16" (8mm) outer diameter fits all CTSC commercial dual-bearing trolleys, 5/16" U-bolt clamps, turnbuckles, and 5.9ft spring brakes.
- Multi-Span Versatility: Available in precut continuous lengths from 100ft up to 450ft to fit any backyard slope, farm acreage, or commercial park layout.

❓ Frequently Asked Questions
Q: What size hardware do I need for this 5/16" cable?
A: Use 5/16" galvanized wire rope clips (saddle clamps), 5/16" heavy-duty wire rope thimbles, and a 1/2" or 5/8" jaw-and-jaw steel turnbuckle to provide adequate take-up tension.
Q: How many cable clamps should I install at each anchor?
A: For 5/16" wire rope, industry standards require a minimum of 3 to 4 drop-forged clamps spaced at least 2 inches apart, with the U-bolt pressing on the dead end of the cable ("never saddle a dead horse").
Q: Can I cut this cable to a custom length?
A: Yes. Wrap heavy electrical tape tightly around the desired cut mark and cut through the tape using heavy-duty wire rope shears or an angle grinder with a metal cut-off wheel to prevent strand fraying.
