What kind of bar do I need?

Dualbell is most commonly used with bars in 5’, 6’, and 7’ lengths, as well as the ez-curl bar.

Where can I get a bar?

As mentioned above, Dualbell is most commonly used with bars in 5’, 6’, and 7’ lengths, as well as the ez-curl bar. But you can also use with other standard barbell types.  
Here are a couple of bars available on Amazon, that we suggest.

You can certainly purchase bars elsewhere or use another you have.  These are only suggestions 

Do I need weight collars?

Yes. We have weight collars available for purchase here separately or in a bundle purchase.  Some bars may include collars or clamps with them or you might use collars you already own.  They should be compatible with 1” standard bars 

How much weight can Dualbell hold?

Dualbell was put through a battery of tests, in-house and by an outside agency, during development and found to be strong and sturdy.  

We recommend loading Dualbell with dumbbells not to exceed 100lbs.

***Important note, beware of tipping when loading heavy dumbbells onto an elevated bar. Tipping weight may differ based on the weight of the bar you are using.***
