The original OSO collars before they were bought out and re branded by rogue. I have owned the orange pair for a decade and picked up the green pair a few years ago in a deal. In my opinion these or the predecessor to rogue USA aluminum collars. Biggest knock on these is from people that don’t understand there is a 2 part process to open them up to remove and add to the bar sleeve. First you unclamp it and then have to apply a bit more pressure to fully open it. Above average hold strength. Purchased in 2016
