Dualbell Factory Seconds – Limited Release

You’ve Already Seen These in Action

Used in Dualbell videos, demos and workouts. These Factory Seconds deliver the same function and performance as our standard Dualbell dumbbell converters—they simply are not cosmetically perfect.

Each Factory Second is fully functional and made from the same durable Nylon 66 with the same protective rubber insert as a standard Dualbell.

What Makes Them Factory Seconds?

The blemishes are cosmetic and do not affect how the Dualbells fit, function or perform during a workout.

• Same patented design as standard Dualbells
• Made in the USA from durable Nylon 66 with protective rubber inserts
• Maximum recommended: one 125 lb dumbbell per Dualbell
• Third-party lab tested up to 1,900 lb
• Fits standard 1-inch bars
• Natural rotation allows comfortable, fluid movement

Factory Seconds are a limited-release, final-sale item. Returns and exchanges are not accepted.

Why Lifters Choose Dualbell

• More exercises from the dumbbells you already own. Add bench presses, squats, deadlifts, rows, curls, overhead presses and landmine movements without purchasing another collection of weight plates.
• Natural rotation. Dualbell rotates freely on the bar, allowing the dumbbells to move naturally during curls, extensions, presses and other exercises.
• Compact and easy to store. Expand your barbell training options without adding bulky plates to your workout space.
• Quick setup. Secure each Dualbell around a dumbbell handle, slide it onto the bar and lock it in place with standard 1-inch collars.
