Engineered for high-tension backyard spans, recreation camps, and adult riders up to 350 lbs. The ZIPEAK 1/4-Inch (6mm) Galvanized Steel Zipline Cable delivers commercial-grade reliability with a massive 6,400 lbs proof-tested minimum breaking strength. Built with a high-density 7x19 aircraft strand configuration and hot-dip Class A zinc galvanization, this heavy-duty wire rope resists sag, weather corrosion, and bend fatigue across spans up to 300 feet.

🛡️ Key Features & Heavy-Duty Rigging Advantages

• Heavy-Gauge 1/4" (6mm) Aircraft Core: 7x19 strand configuration (133 high-tensile wires) balances extreme structural rigidity with smooth flexibility for quiet, low-friction trolley gliding.
• Massive 6,400 lbs Breaking Strength (MBS): Proof-tested to 28.5 kN, supporting a 1,280 lbs safe working load limit (at a 5:1 engineering safety factor) for adult riders, high-speed runs, and longer spans.
• Hot-Dipped Heavy Galvanized Coating: Thick Class A zinc coating shields every strand against rust, road salt, moisture, and extreme seasonal freeze-thaw cycles.
• Extended Lengths for Long-Span Yards: Available in 100ft, 150ft, 200ft, 250ft, and 300ft continuous unbroken spools—shipped securely banded with protective end caps.
• Commercial Trolley Compatibility: Precision 1/4" (6.35mm) diameter fits all CTSC commercial stainless steel trolleys, dual-bearing pulleys, and heavy-duty sheaves up to 1/2" groove depth.

📏 Technical Specifications

🔧 Recommended Installation & Hardware Pairing

• Slope & Sag Guidelines: Maintain a 3% to 6% elevation drop (3–6 feet of drop per 100 feet of run). Heavier 1/4" cable sags less under adult tension, keeping riders clear of ground hazards.
• Clamp Rigging Requirement: Use a minimum of 4 galvanized U-bolt wire rope clamps at each anchor loop (spaced 6 cable diameters apart). Follow the rule: "Never saddle a dead horse".
• Tensioning Rig: We recommend using a heavy-duty cable winch/puller paired with a 1/2" jaw-and-jaw galvanized turnbuckle (4,000 lbs WLL) for fine adjustments.

❓ Frequently Asked Questions

Q: Should I choose 3/16" or 1/4" cable?
A: For runs under 150ft primarily used by kids (up to 200 lbs), 3/16" cable is lightweight and easy to tension. For spans over 150ft, adult riders (up to 350 lbs), or year-round camp installations, 1/4" cable is significantly stronger (6,400 lbs vs 3,700 lbs) and exhibits far less sag under load.

Q: Can I cut this cable to custom length?
A: Yes. You can trim excess cable using heavy-duty 8mm+ wire rope cutters or an angle grinder. Wrap electrical tape tightly around the cut zone first to keep strands from blooming, then recap.

Q: Does this cable work with standard zip line spring brakes?
A: Yes. All CTSC 5.9ft stainless steel spring brakes have an inner diameter that accommodates up to 3/8" (10mm) cable, fitting 1/4" cable with plenty of clearance.
