Heritage & History
Dualbell began during the pandemic, when Glenn Dickstein, a New York-based certified personal trainer and fitness consultant, saw his gym work dry up as clients moved to home workouts. He wanted a way to load the dumbbells people already owned onto a barbell. After his own early versions he called his friend Roy Kushner, an architect, designer and patent holder, who sketched and refined the design; the company says it had a working prototype in under 48 hours.
Glenn, his son Adam Dickstein and Kushner took the patented design to Kickstarter, where New Atlas covered the launch and noted the production version would be injection-molded. The converter hinges at the bottom so it wraps around a dumbbell handle and slides onto a standard 1-inch bar like a weight plate. Dualbell says each converter is rated for a 125 lb dumbbell and has been independently lab-tested to 1,900 lb.
Made in Connecticut
Dualbell converters are injection-molded from Zytel Nylon 66, an engineering plastic also used in automotive and aerospace parts, with a Delrin hinge pin and a rubber insert around the dumbbell handle. In a 2023 write-up, Adam Dickstein described a months-long search that ended with a small manufacturer in Connecticut, where the Nylon 66 is put into an injection mold at the plant.
The brand's FAQ and product pages state that every Dualbell is made in the USA, and its Amazon listings say each converter is manufactured and inspected in the United States.
