Marcy Cast Iron Dumbbell with Vinyl box 14pc - 43lbs

A: Hi JC - Thanks for your question! The handles are designed to support weights exceeding the posted capacity; however, we strongly advise customers to adhere to the specified weight capacity, as the ADS-42 is configured and tested for optimal performance within these parameters. Customers may choose to add additional weight or substitute the provided weight plates with heavier plates, but this must be done at their own discretion. It is critical that the spin lock collars are used at all times and threaded securely to ensure the weights are properly fastened. Impex assumes no liability for any damages or injuries resulting from the use of the product in a manner inconsistent with its intended purpose, including failure to use the spin lock collars or exceeding the specified weight capacity. I hope this helps!
