This Solid steel ball weighs 50 lbs and the chain and locking ankle cuff are 4lbs. The chain length of 4 ft. make this a good working ball and chain. The boy can move around or drag this a little. But he won't be picking up the ball and carrying this one, at least not very far. We like this one a lot! Extra Shipping applies to this item ($30.00 in the USA) Best not to use on your Hard Wood floors or on a Boat.
