How To Plan Your Ninja Course!

Are you looking to buy a Ninjaline, but aren't sure where to begin? Some of the most common questions that our customers have are - What measurements do I need? How do I know which line to buy?  Do extra large trees make a difference? Can we still use the line if we don't have trees in our yard?

 We have all of the answers! Lets start with the basics.

Figuring out which line to buy:

When figuring out where you are going to set up your ninja course, you will first want to find 2 healthy trees that the line will hang between. In order to ensure that you are purchasing the correct length of line, you will want to measure the circumference of both trees, and add this total to the distance between the two trees.

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

Keep in mind that you will want a few feet of spare line to be able to tighten the line using the ratchet system. If you have two trees that are each 3 feet in circumference and 26 feet apart from each other, the 36' kit will work perfectly in your yard, leaving about 4 feet of line to tighten the ratchet.

We have 36', 56', and 40' lines as well as 15' extensions that easily attach to any of the kits. Find out which one works best for you!

 

What to do when you have extra large trees:

Each kit comes with a 6' ratchet strap that will be looped around one tree. Do not worry if neither of your trees are less than 6' in circumference, there are two simple solutions for this!

The first solution is to purchase one of our 10' ratchet straps: https://b4adventure.com/collections/ninjalines

The second solution is to use any excess slack you have in your mainline to cover the left over space around the tree that the ratchet strap is not able to. Please see the diagram below.   

How to set up a Ninjaline without Trees

The Ninjaline has been tested to be set up on trees as well as posts. There are a few things to keep in mind when installing posts into your yard.

First, make sure the ground you will be installing the posts in is a safe, soft area for the Ninjaline to be used over. 

Second, you will want to make sure the ground your yard is sitting on does not contain any underground utility lines or pipes that will complicate the process. You can call 811 for more information on this.

Lastly, we recommend using 6x6 posts made of STRONG wood, such as fir, cemented into the ground at a minimum of 4' deep. 

Here are a few of the tools that will be helpful during the post installation process:

If you have any further questions or concerns regarding the post installation, we highly recommend that you reach out to a local contractor for assistance. Any additional questions about the Ninjalines themselves, please feel free contact us at info@b4adventure.com or 303-339-0482. We are available in our Denver office M-Th 8-5 and Fridays 8-3.
