damage that may have occurred during shipment. Check the contents of your shipment against the supplied packing slip and inform QC
Conveyors of any discrepancies.
If you need assistance, please contact QC Conveyors customer service department Monday through Friday, 8am-5pm EST at (513)
753-6000. In addition, your local distributor has been trained at the factory and can provide support in many ways. You can also visit
