Who invented the screw on collars for ez curl bars?

old EZ Curl bar had collars with a small handle you tightened and a screw would bite into the bar and hold everything in place.

new (chrome plated) EZ curl bar has threads along the area that holds the plates. You have to spin on this huge nut and tighten it against the plated.

With the old bar, a simple 1/4 turn and the collar was off.

With the new bar, it is spin, spin, spin, spin, spin, spin, spin to put on the "collar", and the same in reverse to remove it.

With the old bar everything stayed locked in place until I went to remove the plates.

With the new bar I have to re-tighten the collars after each set.

So this is an improvement?

When are they coming out with the High definition, fully solid state Ez Curl bar?

Sounds like you're referring to an Alun key system Packard.

I think with those they worked well, but obviously if that little bolt type thread wore out at some point, you could be in trouble if a disc or two fell off, mid rep on something.

If you get a collar accidentally loosening, then it will make the weight clunk around a tad, but at least on most occasions, you can finish the set, then re- tighten.

I have a weights kit I've not used for a while, but whilst that loosening could happen, it was not much bother to retighten.

Better than clips. Sometimes those clips don't want to come off, they are fiddly, you end up wiggling them and they can be a pain the arse and a strain on some of the hand and finger muscles.

It seems to me that they fixed something that wasn't broken. And the is not as good as the original.

All they needed to do was make high quality collars for the regular bar. They kept making the collars cheaper and cheaper until they really did not work.

The thing is though, the problem with Alun key collars are, if people lose the Alun keys, or they get lost in a gym setting, you can't use the weight properly again.

That's a big downside.

i personally prefer the spinlock bars it does feel safer to me. but they do sometimes come loose if doing things like cleans.
