This is the whole backyard in one bag. Two sixty-five-foot straps go up between a pair of healthy trees, and fourteen obstacles clip anywhere you like along the top one. The second strap runs low, for walking, wobbling and learning where your balance lives. Everything is rated to 880 lbs, which is less about grown-ups joining in and more about the fact that a child who swings hard pulls much harder than a child who hangs still.

Why it is built this way

What you are getting

  • Fourteen stations, no fixed orderRings, a swing seat, a tree swing, a rope ladder, monkey bars, an arm trainer and monkey fists all move along the strap. Slide them apart for a long easy run, crowd them together for a grip test, or pull three off and leave the rest for tomorrow.
  • Buckles that close in a secondThe one-piece coated buckle is the part we fixed first. It closes with a push, it does not pinch, and it does not need a tool or a diagram taped to the garage wall.
  • Two lines, two difficultiesThe upper strap carries the obstacles. The lower one sits near the grass and does nothing but teach balance, which turns out to be the thing kids return to on their own.
  • Packs into the bag it came inThe whole run goes back into a drawstring pack. Ours mostly lives in a car boot between a park, a campsite and the back garden.

Wonderful for Multiple Ages

I have five kids ranging from 1 to 8 years old. I bought this for them to have another activity outside. All of my kids love to climb and are very active. And they all LOVE this ninja course. I installed this by myself. It took me a little while to put together but I was able to figure it out. Definitely would be easier to put together with two adults. It seems very sturdy and holds all of my kids very well. My kids have hours of fun on this and play on it every day. I definitely would recommend if you have room for this in your yard. I’m very happy with my purchase.

Tough and durable

Great slack line. All obstacles have lasted well against weather and crowds of kids playing on them. If there was a bad thing to mention it is that where the base slack line touches and wears on the trees it will eventually cut through the slack line and break. Ive bought 2 slack lines in the past year. Just ve sure to use the cover that hugs the tree to reduce friction and wear

Asked at the fence

About The 14-Station Line, 2x65 ft

How far apart should the trees be?

Anywhere up to about sixty feet works. Shorter gaps are fine too — you simply end up with more spare strap wound onto the ratchet, and the obstacles sit closer together.

Can it hold an adult?

The hardware is rated to 880 lbs, so yes, though the line is designed around children and we would keep one adult on it at a time.

Do I need tools?

No. The straps thread through the ratchets by hand and the buckles close by hand. A step ladder helps when you are reaching the higher wrap.

Ready to string it up?

Pick the gap in your garden, pick the length that fits it, and let the rest be worked out by whoever is hanging upside down at the time.
