I use a curl bar for lat pull downs, bicep curls and skull crushers.
These attachments looks great but a couple people here have mentioned a foot switch to turn off and on the weights?? sounds great

It works good for curls and skull crushers. You need to buy tonal t-locks and carbiners. The ez curl bar is the only extra accessory I use.
The following EZ curl bar is the only attachment that I use. I have other attachments as I had a home gym before Tonal. But the EZ curl bar is the only additional attachment that I use.

I use this for curls.

Totally agree. The first set of these were borderline painful with how the bar sat on my arms. I almost subbed the movement out of the workout (which you can do if you decide they are not for you). I kept at it and used a towel as padding and that helped. The more I did the movement, the easier it got. I am able to do them without a towel now and since then, I bought a curl bar on Amazon (You'll also need to buy the extra t-locks from Tonal and carabiners) I use instead because it is padded and I feel it is more stable on my arms because of the shape (doesn't want to roll).
Curl bar I bought.

Oh apparently bodylastics (the bands I have) have a bar as well

I came here to link to the one I use (https://www.amazon.com/dp/B07V6Z3171) but the Inspire bar linked below seems way better and it's $30 cheaper.
Note that I have the older model of the Vitruvian with the carabiner attachments.
I'd stick with the factory t-locks if those are aftermarket t-locks. 100lbs is a lot for that little part.
I also like these accessories
Paying $50/mo
The straight bar can be hard on the wrists so I got this
And some of my clothes stopped fitting after I put on 15lbs of muscle
But other than that, it's been great
For comfort, I found this bar helps relieve wrist pressure (using with the T-clips from Tonal)

There are also pads to make front squats more comfortable.
But Tonal is definitely hard. The algorithm keeps you honest and there is no coasting with these workouts. With free weights, I'd get stuck in a rut doing the same weights, but Tonal is always pushing me to my limit which is both good (results) and bad (challenging workouts).
Not quite what you are looking for, but this has rings already attached. https://www.amazon.com/gp/product/B07V6Z3171/

I use this a lot on my lat tower.

As well
This seems to be a favorite. I’m waiting for availability. My wrists like angled vs. straight bar.

It’s not a “smart” curl bar, but seems to be popular among Tonal users. https://www.amazon.com/dp/B07V6Z3171/ref=cm_sw_r_cp_api_i_S9NvFb9QTHP2P
