DA Dumbbell Mold

MOLD ONLY. Sized to create hex head dumbbells ranging from 5-50 lbs. Place a steel pipe of your choosing on the center index and pour concrete to your desired weight and let cure*. Remove, flip and repeat. Mold is not marked so you can place your own numbers for each dumbbell.  Supplies you'll need to buy: concrete, steel pipe, 4" screws & rebar tie wire. *CURING: Concrete takes 24-48 hours to set. For optimal results, de-mold after this time and continue letting your dumbbell cure. Most concrete mixes reach 70% of specified compressive strength after 7 days and full strength at 28 days. **Dumbbells not included; shown for display.**
