When you purchase from Couplemate Trailer Parts, your CRN identification number for this product is located on your Invoice. The CRN on the approval letter will be the same CRN on your Invoice.
Show vehicle inspectors this invoice during inspections of your trailer or vehicle if required.
Furthermore, if you are buying a similar pintle ring coupling without a CRN and your trailer or vehicle is newer than July 2009, therefore, it is not legal to use on Australian roads. Take it back and ask for a refund.
