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
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!

Kids Love It
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!

Works well for intermediate mainline strap hangers too
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).

Finally hooks that keep my grandkids safe.
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.

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