SD03 Cast iron Adjustable Dumbbell 5-100lb OEM with Contoured Handle

Better than plastic ones as cast iron adjustable dumbbells are smaller, stronger, and solid. You can adjust the weight easily by adding or removing the plate when needed that helps to save a lot of money. They are great sets if you want to use different weights for different exercises. The plates not being used on the bar can be used separately as they are still easy to hold.

The dumbells are strong and durable plus great finish quality. Weights are tight, steady, and do not rattle. Pretty straightforward to assemble.

Construction of high quality cast iron and strictly casting process. Logos and OEM designs can be added to our service.
