I didn't use the slack line but bolted these into joists for an indoor ninja course. Great stuff and holds my 225 no problem.

I look forward to what this will do for my grip. The rope is thinner than I hoped so not sure how long they will last.

Great addition to the ninja line. These definitely made it challenging for the boys!

I've bought other items of theirs and liked them very much. It might have just been the ones I got but, the Red one pulled much longer once tighten then the blue one did. So they are not the same length. Blue one is a fill inch shorter than the Red one. Makes my OCD hurt, but otherwise seem to be high quality, otherwise I would have rated higher.

Its exactly as it says. The only complaint is the material is painful to the hand. But my husband says thats part of getting your hands stronger. Otherwise it works great.

Have had these up for more than 6 months and the durability is fantastic. Will purchase from this seller in the future.

Un poco alto el precio, pero cumplen su función
