In addition to the obvious benefit of being able to determine the product's warranty status, an Invoice number may be helpful in determining the potential cause of any problem you may be having.

Our system will give us complete details about the product you were shipped as well as a digital photograph of the contents of your shipment. This is a part of our new Quality Control procedure, but it also comes in quite handy if you are experiencing problems that may be related to the brackets or installation kit. Naturally the invoice also contains the item's serial number and other helpful information about the item(s). Pretty cool huh?

If you don't have an invoice number, just provide the information requested about the dealer where it was obtained... Yes, even if the dealer was Corbin. We will attempt to locate the information on our end.
