Yes, if the existing structure can support the added weight. Please contact a qualified sports contractor or structural engineer to assess your buildings capabilities to support the new weight loads. We take into consideration the size of the mast and supporting structure the backboard is mounted to, the distance from the wall for side swing units, the anchor points in the wall. We also look to see if the current unit is a recognized distributer. This helps us to know the quality of the unit for things like welds and materials. Any work that is done on your unit should always come with a full maintenance check. This should include looking at all bolts to ensure that they are whole and not worn through with friction over the years, re-lubing all pivot points, looking at all the steel cable to make sure it is not frayed anywhere. There is more to the inspections, but that is a general starting point.
