Review: Durable hardware - 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!
Review: Work well as advertised. Easy install. - 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.

### ⭐⭐⭐⭐⭐ Durable hardware
*by B***Y on September 18, 2025*

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.

### ⭐⭐⭐⭐⭐ Work well as advertised. Easy install.
*by M***S on January 2, 2026*

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.

### ⭐⭐⭐⭐⭐ Works well for intermediate mainline strap hangers too
*by D***S on October 20, 2025*

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).
