Rubber (urethane) Coated Hex Dumbbells Feature durability that simply can't be matched. It resists cracking and fading while protecting floors and equipment. Made from solid cast iron with a 6-sided anti-roll design and encased in virgin rubber, this dumbbell is stylish as it is durable. Heads are securely fastened with a uniquely designed pin mechanism that means this equipment is about as low-maintenance as it gets. No spinning or loosening. Rubber Coated Dumbbell System combines one-piece cast iron heads with steel inserts that have been pinned, press-fitted, and welded. The weights' compact design makes them shorter in length and easier to work with than conventional dumbbells, while a durable rubber finish protects both you and your workout area.
