Go HeavierβWith Collars Included
The Dualbell Superset + Collars uses four Dualbell dumbbell converters so you can load two dumbbells per sideβreaching weights a single pair of dumbbells cannot.

Why Lifters Choose the Dualbell Superset + Collars
- Go beyond your heaviest dumbbell. Load two dumbbells per side and combine different sizes to create weights a single dumbbell pair cannot provide.
- Everything needed to secure it. The included quick-release collars lock the Dualbells in place and release with one squeeze.
- Progress in smaller increments. Mix dumbbell sizes to add weight gradually instead of relying only on traditional plate increments.
- Natural rotation. Dualbell rotates freely on the bar, allowing the dumbbells to move naturally during presses, rows, curls and other exercises.
- Built for serious training. Each Dualbell is made in the USA from durable Nylon 66 and is recommended for dumbbells up to 125 lb. Third-party lab tested up to 1,900 lb.
- Compact and easy to store. Four Dualbells, two spacers, the collars and storage bag take up far less space than another collection of weight plates.

Great product expands my workout routine in an exciting way. Owner provided exceptional customer service and inspiration!
Ingenious!
Just started using the Dualbells and they work great! In my current workout, I'm able to use them to do Shoulder Press, Bent Over Rows, Skull Crushers, Standing Curls, Hip Thrusters, Romanian Dead Lifts, and Calf Raises. For Hip Thrusters, I use a pair of bumper plates along with the Dualbells and it works perfect (had to get adapters for the plates to fit my 1" bar). I've never used a barbell before and it's so fun to be able to do something different with my workouts. Great product!!!
Really great product! Fits my 60-inch standard CAP barbell perfectly. Both the converters and spacers slide on easily, and thereβs no noticeable issues with dumbbell rotation while lifting. Works well for a wide range of barbell and landmine exercises. I especially like that I can attach two pairs of dumbbells, which makes my collection much more useful. This alone makes the superset a better value than other products that attach dumbbells onto barbells. The plastic feels sturdy. I'm not one to slam things so I don't have any worries about durability. Overall, highly recommended. I'm glad to be able to incorporate more weight into my exercises.
Communication was superb, responsive and quick, and super helpful with my order. Super fast, careful shipping. The products are durable, high quality and excellently machined and a great way to maximize the utility of dumbbells in a space-saving way.
Very pleased with mine, does exactly the trick required for my home gym.
Decent space and money saver as I don't have to buy additional plates and can use existing dumbbell set.
My dumbells go up to 30kg, I have the adapter 4 pack and put 30kg & 27.5kg together on each side of the bar (115kg in total)- it all feels solid and holds up well.
Would recommend
