Turn fixed or adjustable dumbbells into weight plates for a standard 1-inch bar. Secure a Dualbell around each dumbbell handle, slide it onto the bar and lock it in place with a standard 1-inch collar. You’re ready for bench presses, squats, deadlifts and more—without buying or storing another collection of weight plates.
The Core Setup includes two Dualbell dumbbell converters—one for each side of the bar. Already have standard 1-inch collars? You’re ready to go. Need collars? Choose the Pair + Collars bundle and save compared with buying them separately.
