Though the Slackline and Ninjaline are both made of the same material and feature the same ratchet system, they are still unique from each other. The Slackline is designed to be mounted just a few feet above the ground for the purpose of balancing on as you walk across, and the Ninjaline is meant to be mounted higher above the ground. It features integrated sewn in pockets and delta clips that can attach Ninja obstacles onto your line. If you are looking to build your own Ninja obstacle course, we recommend purchasing the Ninjaline. If you already have a Slackline, we recommend using our Ninja Grip Clips to build your own makeshift Ninjaline.

Take a look at our durable Slacklines. They are made of the same material and include the same ratchet system as the Ninjaline, making for an easy installation.

We recommend consulting with an engineer or contractor to determine the "side load" strength of the two points you will be attaching your line to. Some Ninja families have even found ways to install the hanging obstacles directly into a ceiling so no line is needed! We love to see you think outside the box, get creative and have fun. But whatever your idea is for an indoor Ninjaline, whether it’s in the garage or basement, remember to consult with an expert for safe installation.

This diagram shows you how to use excess line from the mainline to help reach all the way around your large trees. 

Simply, measure the circumference of the two points you will be hanging the line on. Add the circumference to the distance between the points. You always want to purchase more line than necessary so that you can use the extra slack to tighten and secure your line. Too much line is not an issue, as we provide special ratchet covers that fasten securely around the ratchet and excess line. Follow the equation below: 

Circumference of Tree #1 + Circumference of Tree #2 + Distance between Tree #1 and Tree #2

t is best to know your tree’s dimensions and your course length before making a purchase. But, when you do not have enough line, call our customer service representatives, and they will help as best they can. To solve this issue with as little hang up as possible, purchase the 15' Ninjaline Extension.


StairSlide nests (overlaps) on top of other StairSlides so they can extend to cover more stairs. In other words, you can use a single StairSlide on the bottom three stairs or use four StairSlides to cover approximately nine stairs. It all depends on your appetite for thrill. StairSlide's patent-pending, self-anchoring design uses unique features to help prevent it from moving during use without the need to permanently install StairSlide on your stairs.

Not all stairs are alike. And since there's no way for us to know your stairs' measurements we can only offer a recommendation based on user feedback. One StairSlide typically covers the first three steps. Because they are meant to overlap, add one StairSlide for every two steps after that. Our popular 4 pack covers about 9 stairs—a great start for any StairSlide career!

Naturally, there’s inherent risk when you use any slide, but it’s worth the risk. StairSlide is certainly safer than other ways we’ve slid down the stairs (e.g. laundry basket, mattress, cardboard box, family cat, etc.). Remember, the longer the slide the faster you'll go. And bend at the knees when you land on your feet! Landing on your bum is not recommended.

That's kind of a heavy question. Ongoing field testing has yielded promising results: We recommend StairSlide for ages 3-12 even though it can support a person up to 175 lbs without showing signs of structural weakness. We will continue to make recommendations that help ensure the safety of our users.

There are a couple of factors that determine your StairSlide’s speed:

What’s your stairset’s incline?If your stairs are somewhat on the steep side, this will translate to your StairSlide.

How many sections make up your StairSlide?The longer your slide is, the faster it’ll be; for example, a two-section StairSlide will be slower than a 4-section StairSlide.

If you’re worried your StairSlide is too fast, there are measures you can take:

Leave a step uncovered at the bottom of the StairSlide.When you think of a standard playground slide, the end never goes straight to the ground; there’s usually at least a foot of space between the ground and the bottom of the slide.
+ For younger kids, they can slide on their belly feet first.

Cushioning counts. Going fast can be fun! But going fast without the proper cushioning? Not so fun. Pile the softest, plushest pillows and the comfiest couch cushions at the bottom of the StairSlide.

For younger kids, try sliding on the belly with feet first. Toddlers learn to go down the stairs by crawling backward; so, if your child isn’t comfortable sitting up on the StairSlide, they can still have fun sliding on their belly!

Use the Low Impact setting. 
The StairSlide can be set up in two different ways: High Adventure & Low Impact. High Adventure is the standard setup, but Low Impact allows the slide to end on a slower gradual slope. For visual depictions of the two setups, read our blog post, More Than One Way to Slide

Each StairSlide is approximately 43 inches (109 cm) long, 19 inches (48.3 cm) wide, with a 13 inch (33 cm) seat. A single StairSlide weighs just over five pounds (2.4 kg).

Yes. And StairSlide does not damage non-carpeted stairs when used properly.

StairSlide is made from durable, lightweight polypropelene. Polypropelene is impact-resistant and able to withstand heavy use as well as has some added flexibility. Oh, and magic fairy dust!


Simply, measure the circumference of the two points you will be hanging the line onto, and add that number to the distance between the points. It is better to overestimate the length of cable you will need as there are no extensions for the zipline. In the case of excess cable, you can cut off the extra that you are left with, or wrap it safely around the tree.

Circumference of Tree #1 + Circumference of Tree #2 + Distance between Tree #1 and Tree #2

The turnbuckle conveniently attaches to either end of your Zipline. To install the turnbuckle, simply attach one eye bolt to one of the looped ends of the cable; either the pre-looped end or the loop that was made from the u-bolts. Next, attach the other eye bolt end of the turnbuckle to the two loops from the sling cable that is wrapped around the opposite tree. Twist the turnbuckle to fine-tune the overall tightness of the Zipline course, and adjust occasionally so the cable stays tight.

The first and easiest option, which happens to be our favorite, is the Zip Quick Ratchet Installation. This system makes tightening the cable easier than ever and simplifies the installation so much that you could even do it alone! Additionally, in order to tighten the zipline with ease and success, set up the turnbuckle, sling cable end first, attach the U-Clamps to the loop on the opposite tree (make that loop as tight as you can), then use the turnbuckle to tighten even more.
