Our Black Hex Dumbbells adopt injection‑molded TPE or TPU outer shell, odor‑free, wear‑resistant and durable for heavy‑duty training. Hexagonal heads prevent dumbbells from rolling away during workouts. Three handle versions for your choice: hard chrome‑plated, zinc‑plated and stainless steel handle. These dumbbells work great for both home gym and high‑traffic commercial fitness centers. Various weight grades satisfy all‑level strength training demands. We provide full OEM & ODM service. You can select outer material, handle type, and request custom logo & colors. Wholesale inquiries from gym distributors are warmly welcome.
