The Iron Grip Barbell Company introduces Urethane-encased Solid Steel Dumbbells and Fixed Barbells.
November 1997, Costa Mesa, CA These unique, American-made, heavy-duty dumbbells and barbells are maintenance-free and carry a 5-year guarantee against breakage. The inserts are produced from precision machined steel handles and drilled, chamfered and machined heads, welded together to produce a Solid Steel insert which is then encapsulated in durable, heavy-duty Urethane. Iron Grip Urethane dumbbells feature a unique, patented 12-sided anti-roll design. They have no sharp edges and feature a flat head, providing a comfortable, stable and tip-resistant surface. They are far smaller (in length) than imported, bolted together rubber dumbbells, are highly impact resistant and exceptionally durable. Urethane offers enhanced bonding (vs. rubber) and will not split, peel or delaminate from the insert. Further, these dumbbells will not damage equipment, walls or floors, nor will they mar equipment (leave black scuff marks) like rubber. Available with the weight permanently engraved and painted on each head, the Urethane line includes a choice of 5 different dumbbell handles or 4 different fixed barbell handles
