The 4x48" package has 4 straps that are roughly 50" each from end to end including the clamp (as advertised). I was not familiar with brine yarn and was wondering if it would stretch - it doesn't seem to. I'm using these to tie down some satellite speakers (6x10x10) to some Gator monitor stands. The clamp seems to hold the tension well and they are working as intended. I needed about a 40" wrap around so the 48" length is perfect for my needs. Hard to find cargo strapping this short. Don't have any run time, so can't talk to reliability. But they look and feel solid, and I'm not concerned about the quality. I like them!
