Made in the USA from highly durable nylon plastic, Rogue Proloc™ 1 Collars attach firmly and securely to a wide range of both general and specialty bars, making them among the most versatile and reliable weight lifting collars on the market. The Proloc™ 1 features easy on / easy off knobs that work as smoothly as most spring clips, while offering a more consistent, locked-on hold during even the most intense power lifting routines. Compatible with Olympic bars and Powerlifting bars-- as well as most logs, cambered bars, Swiss bars, and safety squat yoke bars-- these are legitimate universal collars that can serve an entire weight training facility for years.*

These are awesome! Quiet, quick, and sturdy. I actually let a kid use them and he stripped out the screw. I bought a cheap tapping set and rethreaded the hole (took about 10 minutes) and it works as good as new! I think these deserve more love and I usually grab these over the Rogue or Titan collars. They should get more credit. They even fit decently onto an axle/log!

Am I so lazy that I hate these collars for simply taken a few more seconds to put on the bar ? Yes .. yes I am. Also don't like the aesthetic of them

These work ok but I find they loosen very easily and are time consuming to get on and off. Bought them for an axle but I find my regular collars work better on the axle anyway.

These can be LOCKED DOWN on the bar. Good collars from keeping weight on. I am not a fan of the twist mechanism, but they will work on normal and axle like sleeves. It doesn’t feel cheap, but it’s not comfortable or convenient. For the price either go cheaper with a budget lockjaw or high end like rogue USA aluminum. The chain version of these I do like a lot.

I love how secure these are on any of the barbells I use (including the SSB yoke, powerlifting bar, axle bar, etc.) and that they have magnets built in so I can keep them on the rack at all times so that I don't lose them.

Ever since I bought these, they have been the go to collars in my gym. They work on speciality bars (elite fts ssb, axle bars, etc.) and all regular power bars. Easy to take on and off and easily clamp them down. I bought the magnetic ones which keeps them aligned with the plates on the bar, and easy to stick to the rack as you load plates.
