NordicTrack 55 Lb. Select-A-Weight Adjustable Dumbbells (NAMSDB20)
Lifters happy to start at ten pounds per hand
A pair of selector dumbbells giving 15 settings per hand between 10 and 55 pounds, with moulded storage trays included and a matching stand sold separately. The 10 pound handle bar sets the floor of the range, and NordicTrack does not publish an owner's manual for this model online.
Published specifications
- Maker page: model NAMSDB20, 15 weight adjustments per dumbbell
- Maker page: adjusts from 10 lb to 55 lb; 10 lb handle bars
- Maker page: storage tray included; stand listed separately

- Listing: sold as a pair, 11.4 x 19.4 in, 1.25 in handle diameter
- Listing warranty text: two years, repair or replacement, shipping paid
Strengths
- Fifteen settings per hand with a single selection system
- Storage trays are included rather than sold separately
- NordicTrack publishes the exact model number on its own page
Caveats
- Nothing lighter than 10 pounds, because the handle bar alone weighs that
- No NordicTrack-hosted manual found, so no published safety or care rules
- The stand that raises them off the floor is a separate purchase
