Ninja Warrior Obstacle Course Accessories New Upgraded Buckle for 2” Width Slackline No Tearing Slackline，Quick Buckle – No More Threading，Install in Seconds – Anywhere on the Line

I really do love these little hooks. They were very simple and did slide easier than the ones that came with my original set. What I will mention is that you cannot put them on if the line is tight. You must loosen up your ratchet line so that it has some flexibility to it before you'll be able to put these on. So keep that in mind when you're adding them. I'd recommend putting a ton of extra ones on when you first build it so that you can add additional accessories without having to constantly take the strap down. Overall, the quality of these are very nice powder coated and stainless seem to be holding up pretty well. They're extremely durable for a long time. Use outside. And they did fit very securely onto our existing strap. Overall, this is one of the most fun activities my kids have in the yard and doesn't require much attention from me so they can just go out and enjoy it at their own leisure. I love that these keep the accessories from sliding and the locking mechanism on the hooks keeps items from falling off on expectedly, which makes it much safer than some of the other options.

These work really well. Easy to put on and take off as long as the strap isn't under tension. They slide easily on the strap until it has a lot of tension then it doesn't move.

Bought this as an add on to another product and it turned out to be a great product by itself. Easy to assemble and very solid for small children (my 8 year old grandchild is the perfect size and weight). Definitely gets the children outside to play!

These were the final and most important part of the puzzle, to complete my makeshift swingset. They are quality and easy to add to a slack line. It takes a bit of patience getting them in just the right spot, but they easily slide along the slack line when it’s not tight. My kids absolutely adored their swings. It’s easily becoming some of the best money I’ve spent on a toy!

Great for Grandma's house. Easy to assemble. Grandkids didn't even come inside to play when they had this to play on. When they go home, I just store it away until the next visit.

Great for hanging additional obstacle items, but also works very nicely for adding mid-point supports for the mainline. Can use chain or rope guylines to provide mid-line support to the mainline to prevent-reduce sagging, can help reduce how high the mainline needs to be hung, and reduce tension of the mainline (only when additional support points are available above the line, of course, such as an indoor course).

Slip on black brackets do not stay attached to vinyl strap once weight applied.

These are very steady and takes away the fear of the hanging stuff won’t come off. It seems more secure. I don’t get worried if the kids will fall . Others just didn’t give me the security for my grand kids to hang from ninja gym like these do. I recommend them for sure.
