Oh, nice, thank you for the tip! But still, I need to find something universal, for any type of dumbbell. I do have something on my mind, I will share it soon.Home - db capper
Strong Designed to support well over 100 pounds safely and comfortably. Lightweight At just over 1/2 pound you won’t even notice it’s there. Effortless The aluminum quick clamp makes it fast and easy to put db capper on and lock it securely in place, even with one hand. Universal Works with...dbcapper.com
Then just set on its end on a plyo box. Hex/pro style will still be way easier to deal with but it’ll work.
Looks like the DB capper went out of business so I’m not sure if there is another 1” bar solution out there.
