This item was used for a common house supporting beam that is in my garage. Turns out the trolley will barely fit the beam. Be sure your beam is not too wide to fit between the roller flanges. Also, the through shaft that holds the halves together and the hook-eye, includes two nuts you lock together (I used Loctite red on them as well), instead of the self locking castle nut shown.Overall, the unit is substantial and I would expect it to hole a ton as rated. But note that the beam has to be able to support a full ton on its flange or you risk serious injury. I did not receive any installation information and the box looked opened and re-taped, although it may have simply been taped due to the weight of the object All parts were included.I am using it with a 1-ton chain hoist.As a one ton beam trolley, I would recommend it as long as the safety rules are followed. I do not consider it "heavy duty".
