Dualbell Superset Upgrade Kit

Turn Your Dualbell Pair Into a Superset

Already own a Dualbell Pair? This upgrade kit adds two more Dualbell dumbbell converters and two interlocking spacers, giving you the four-adapter setup needed to load two dumbbells per side.

Combine different dumbbell sizes to go beyond the weight of your heaviest pair or progress in smaller increments. Add a 50 lb and 30 lb dumbbell for 80 lb per side, or mix other sizes using the dumbbells you already own.

This is an upgrade kit for existing Dualbell Pair owners. It is not a complete Superset package.

Quick facts:

• Expands an existing Dualbell Pair from two converters to four
• Allows two dumbbells to be loaded per side
• Maximum recommended: one 125 lb dumbbell per Dualbell
• Combined recommended capacity after upgrading: up to 500 lb across four Dualbells
• Fits standard 1-inch bars
• Natural rotation allows comfortable, fluid movement
• Made in the USA from durable Nylon 66 with protective rubber inserts
• Third-party lab tested up to 1,900 lb

What’s Included in the Upgrade Kit

• 2 Dualbell dumbbell converters
• 2 interlocking spacers
• Drawstring storage bag

Your original Dualbell Pair, bar, dumbbells and collars are not included. Standard 1-inch collars are required.

Why Upgrade to the Superset Setup?

• Go beyond your heaviest dumbbell. Combine two dumbbells per side to create weights a single pair cannot provide.
• Progress in smaller increments. Mix dumbbell sizes to add weight gradually.
• Keep using the equipment you own. Expand your barbell and landmine options without purchasing another collection of plates.
• Natural rotation. Dualbell rotates freely on the bar, allowing the dumbbells to move naturally during presses, rows, curls and other exercises.
• Compact storage. The two additional Dualbells, spacers and bag take up far less space than more weight plates.

Will It Fit Your Setup?

Dumbbells: Dualbell fits dumbbell handles with at least 4.25 inches of usable length and a diameter of up to 1.38 inches. It works with most fixed dumbbells and many adjustable models. See our Adjustable Dumbbell Compatibility Guide for confirmed brands, fit notes and measuring instructions.
