Perfect attachment to my 2x2 power rack. Works perfectly!!

Product was missing 1 x washer.
Had too source this separately…
When retracting it doesn’t have a plastic stopper so the mono arms bang on the attachment.
Attachment arms are also not as snug against rack. I will need to glue plastic to make it make it more snug
I am sceptical on how these will go with 1rm testing.
Slightly disappointed…

Work just as expected, big help

The collars don't have as much range as others on the market, but does the job sufficiently. I had to stick put two rubber pads where the arms contact the frame upon release of the bar to dampen the load bangs. My only issue was that the instructions call for 4 washers, but we were only provided 2 washers. The parts bag stated that there were only 2 washers so there is a disconnect between the installation instructions and the items provided. We had plenty of washers lying around so it wasn't an issue for us

Have been using them for 8 months now. Very happy I bought these, they are fantastic. Yes, they are bulky and noisy when the hooks fall out of the way but functionality and safety easily makes up for this. This is such a great device to protect joints as no steps under load are required.
