Install and tension your backyard or commercial zip line with speed, safety, and zero stress. The CTSC Zipline Cable Tensioning Winch Kit delivers 660 lbs (300 kg) of mechanical pulling leverage, allowing a single person to effortlessly pull steel wire rope taut and eliminate mid-line sag. Complete with an 8.2ft heavy-duty tree anchor strap, a 4ft spooled steel cable puller, and a forged parallel jaw cable grab clamp, this come-along winch holds cable under rock-solid tension while you torque down your permanent U-bolt clamps or turnbuckle hardware.
🛡️ Solo Installation & Mechanical Highlights
- 1-Person Solo Installation: Eliminates the struggle of multiple people manually pulling cable against tree anchors. The ratcheting winch mechanical advantage does all the heavy pulling for you.
- 660 lbs (300 kg) Working Pull Capacity: Delivers ample mechanical force to tighten residential spans (60ft–250ft) and commercial runs (up to 500ft) without straining.
- Forged Parallel Cable Grab: Heavy-duty self-gripping clamp securely bites onto 3/16" (5mm) up to 1/2" (12mm) wire ropes without crushing, kinking, or stripping the galvanized steel coating.
- 8.2ft (2.5m) Heavy-Duty Anchor Strap: Broad polyester webbing wraps securely around large anchor trees or posts without cutting into bark or slipping.
- Dual-Pawl Safety Ratchet: Precision gear teeth and spring-loaded dual locking pawls ensure cable tension cannot accidentally slip or release mid-rigging.
- CE & RoHS Certified: Manufactured to stringent industrial standards for reliable, multi-year rigging performance.

🔧 How to Use in 4 Simple Steps
- Anchor: Wrap the 8.2ft strap around the finishing tree and attach the ratchet winch frame.
- Attach Cable Grab: Clamp the parallel jaw grab onto your main zip line cable approximately 3 to 4 feet in front of the anchor.
- Tension: Crank the ratchet handle to pull the cable taut until you reach the desired slope and sag.
- Lock Down & Release: Install and torque your permanent U-bolt clamps and turnbuckle around the tree. Once secured, release the winch tension and detach the kit for storage.
⚠️ Pro Operator Tip: When releasing the tension after your permanent clamps are bolted down, open the ratchet handle completely flat. If it feels stiff under heavy line tension, gently pull the spring-loaded release catch in the opposite direction of the drive gate to disengage the ratchet drum smoothly.

❓ Frequently Asked Questions
Q: Does this kit stay on the zip line permanently?
A: No. This is a temporary rigging tool used during setup or seasonal maintenance. Once you pull the cable taut and tighten your permanent wire rope clamps and turnbuckle, you disconnect the winch kit and store it away.
Q: Will the clamp damage my galvanized cable coating?
A: No. The parallel clamping jaws distribute gripping pressure evenly across a wide surface area, locking onto the cable without crushing individual wire strands or peeling the zinc galvanization.
Q: Can I use this for retightening an existing zip line that has sagged?
A: Absolutely. It is the fastest, safest way to take out slack after a season of heavy riding or natural tree movement.
