Just got these and tried them out immediately. They work perfectly on my farmer carry bars. Easy to put on and take off and the plates don't budge. As a bonus, red happens to be my favorite color and it really pops with the black lettering...

These collars are made well and are very sturdy, but I am honestly not sure how necessary they are. The difference between these and the Rogue HG 2.0 barbell is an eighth of an inch in width, and 2/25 of an inch on inside diameter with the Axle Collar being the smaller one. Apparently not recommended by Rogue, but they can be used on regular barbells but require a lot of force to latch closed. I find this is also the case for using these collars on the recommended bars such as the Axle Bar and LB-1. The force required is so great on these recommended bars that the collar's latch can and will smack or pinch your hand and hurt. The regular HG 2.0 collars work just as well and maybe even better than these Axle collars, just purely based on the lower forced needed to close them. Though I will say that the tightness does help in keeping plates straight and on the bar during exercises where the bar is dropped from overhead. However if you have the HG 2.0 or have the HG 2.0 in your cart, I'm not sure these are worth the extra $40 and taxes unless you like red.

Bought these last year and haven't been able to use them once. They don't fit any bar at either gym I go to. Wasted 40$ you're better off buying the classic spring clips.

Bought these collars for my Rogue TB-2 Trap Bar and they do not fit.

Get ready to injure your fingers they snap and bruise your hands. If you’re not prepared horrible colors I do not recommend.

Bought these because I like using the hex bar for deadlifts and the gym doesn't have clamps to fit this smaller diameter bar. Rather than struggle with plates threatening to slide off, I bought my own. These are solid and secure and do the job perfectly!

Stout little suckers. Slap them on the trap bar and flex when the wife walks by in the gym — both me and the collars looking good. Zero slide from the collars, perfect compression on the sleeve — not to hard to push the tan down, and not too easy — perfect Goldilocks. Orange color is nice and flashy.

Got these so my wife could do herself. We were using the old school spring style which are easier to remove than these. They clamp so tight be careful when removing. The older version of this product was great. Used at the gym for years.
