    What slope is recommended for my zip line?

    We recommend a vertical drop of 6-8’ for every 100’ of ride. For example a 150’ long zip line will work best with a drop of 9-12’ from end to end. A slope steeper than 8% of the length is still possible but may require a larger braking system. 

    How does the bungee brake work?



    What it is: The bungee brake consists of a block on the cable that resembles a small brick but is free to slide up and down. A bungee cord is connected between the block and anchor point (usually a tree or post) off to the side of the zip line.  How it works: When the rider comes zipping down the cable, the pulley will make contact with the block, pushing it down the line, this in turn stretches the bungee cord providing resistance. The brake slows the rider to a gentle stop near the end of the cable. For better explanation check out our video at

    What size should my zip line tree/anchor be?

    The size of the anchor recommended varies based on the length of ride, the sag in the cable, and the type of application. In general we do not recommend anchoring to a tree less than 12” in diameter.

    Can I attach accessories to the pulley?

    Yes! All of our pulleys allow for easy attachment to a variety of accessories, including seats, handlebars and harnesses. (A carabiner is required for attaching most accessories.)

    What is the maximum stretch of your 1/2” bungee cord?

    Our bungee cord shouldn’t be stretched beyond 75% -100% of its actual length. So if the weight of the rider causes the 20ft cord to stretch 35-40ft we would suggest doubling up your bungee or purchasing an additional length of bungee cord to double the strength of the brake system.

    How soon can you ship out my order?

    We typically ship all orders within 24 hrs. We are often able to ship out products the same day they were purchased. See our shipping page for more details.

    How long will it take for my order to get to me?

    Are zip lines really popular enough to support your business?

    You bet they are! We’ve seen the interest in zip lines grow immensely over the years we’ve been doing business. Folks around the world call in with questions about how to install a zip line and what kind of gear is necessary. We’re committed to providing the information and the products needed to be a part of this exciting industry. Check out our blog to see how other folks are enjoying our zip lines!

    What’s the difference between your three zip line kits? (The Viper, Viper Deluxe, & Quicksilver kits)

    The Viper Standard kit is our most basic kit; it is perfect for a small to medium backyard.
    The Viper Deluxe kit includes everything in the basic package with the addition of a carabiner, lanyard, a harness and a bungee brake system.
    Our Quicksilver kit is designed for longer distances; it includes a larger sized cable (5/16" cable), an additional cable sling and turnbuckle(5/8" x 12"), the removable Quicksilver pulley, and a longer braking system. Also included with this kit is a carabiner, lanyard and harness.

    Which cable is better for my zip line? Stainless steel or galvanized?

    • Galvanized is stronger than similar diameter stainless.
    • Galvanized is 2-3 times less expensive than stainless (think of it this way, you could purchase 2-3 zip line cables using galvanized cable for the same cost it would take for one zip line using stainless steel).
    • Galvanized is very weather resistant. Unless your location is next to the ocean (salt spray in the air causes corrosion) then the galvanized will last many years. Depending on use, expect 5-10 years.

    What’s the weight limit for a zip line?

    All of our zip line kits can accommodate a maximum load of 350lbs. With any zip line, the weight limit depends on the size of cable, turnbuckle, pulley, and riding gear. Never ride a zip line without first testing for security. Inspect all the related gear for defects, send a heavy object down the zip line, and safely test your own weight at the lowest point of the zip line. For further questions, call us at 1.888.476.3701 or contact us here.

    Does my zip line require any maintenance?

    Zip lines require very little maintenance. Main items such as the cable and turnbuckles are galvanized which makes them very weather resistant. Oiling your cable is not necessary. To extend the life of your riding gear (pulleys, seats, harnesses, etc.) we recommend storing them in a dry location when not in use.  

    What does the speed rating on the pulleys mean?

    All of our pulleys feature a mph speed rating. This rating refers to the maximum speed the bearings are capable of handling without overheating or experiencing damage. The speed rating is not an indicator of the actual speed you are likely to see on your zip line. The slope of the ride rather than type of pulley used primarily determines speed.

    Who can set up a zip line?

    Zip lines are much easier to setup than most people anticipate. Anyone with basic handyman skills is fully capable of installing a typical zip line. All our kits include installation instructions. We are also happy to provide technical support over the phone at 1.888.476.3701. For extreme lines or commercial applications seek professional advice.

    Any tools required for my zip line?

    A wrench and a ladder may be needed for installation. The wrench, to tighten down your cable clamps, and a ladder, to reach the height of the cable. Zip lines over 150’ long will also need a Tensioning kit for installation. See our installation tools.
