<b> Outdoor Fun For everyone! </b> <br> <br> Our Double Obstacle Line - Deluxe version has been designed to provide hours of outdoor fun for children ages 5 and up, and will support users up to 200 lbs. It's a Ninja warrior course with monkey bars, hanging rings, swing, climbing rope and hanging monkey knots that is completely adjustable, allowing you to adjust the skill level of the course for different ages. Unlike any other ninja slackline set out there, our patented double line design allows for the monkey bars to hang as monkey bars should: <b> perpendicular to the course </b>. And we are able to do this using a single slackline and just two trees, no need for extra trees or posts. <br> <br> The Double Obstacle Line is designed to be used between two healthy trees that are spaced at least 15 feet apart, and no more than about 37 feet apart. We recommend trees between 1 foot and 3 feet in diameter. <br> <br> A loose formula to determine if your trees are too far apart: Measure the distance between the center of your two trees and multiply by two, then add 1/2 the circumference of each tree. If the total is greater than 79 feet, then your trees are too far apart for our set. <br> <br> We also do not recommend the use of posts or man made structures in place of the trees, due to the high forces involved once the line is ratcheted into place. <br> <br> <b> The set includes: </b><br> - One eighty foot slack line with heavy duty ratchet and installation accessories <br> - Three monkey bar obstacles <br> - Four hanging ring obstacles <br> - Two monkey knot obstacles <br> - One monkey bar with gym rings attached <br> - One swing <br> - One climbing rope <br> - Two tree protectors <br> - One storage bag, for easy storage of your obstacle line when taken down <br> <br> <b> Add to your cart and buy now! <b>
