This magnetic weight attachment is designed specifically for the REP x Pepin Dumbbell Series, allowing you to use the full range of Micro Gainz Fractional Olympic plates (0.25 lb to 1 lb) for finer weight adjustments and more precise progression.
The attachment mounts to the dumbbell's dovetail feature using embedded magnets and can also be wedged into the dovetail for additional retention and security during use.

Magnets are press-fit into the integrated circular recesses
