Old shoulder injuries and reconstruction surgery were keeping me from the low bar position but I really didn't want another bar just for squats. After seeing an old post on the Starting Strength forum discussing some metal handles you could attach to your bar I decided to make some. Sounds crazy but they work on any bar.
8mm climbing rope (aka prussic cord).
schedule 40 PVC 1" pipe
I reinforce the knot with some zip ties
You can place them at a comfortable width and adjust the length depending on shoulder mobility
It took a few workouts to settle in to a neutral wrist position with the weight supported on your back in the low bar position.
Disclaimer: I'm 72 yo and don't get past the low 300s for squats but I would not hesitate to go higher if I was stronger. I've been using them for about 10 years.
When my wife gets home I'll get a photo in use.
