We do not have the measurement in our records and because it is on back order the manufacturer can not measure it until it's back in stock. I recommend contacting us at the end of next week (12/14/2012) at 1.888.388.6372. World Cuisine is due for a shipment of these jar wrenches at that time. Sorry for the inconvenience.
