Please note: although the front of these ears have standard rack hole spacing, there is no standard for the side holes. Spacing of side holes on rack ears like this depends on the manufacturer and model number of the product that the ear is made for. On these rack ears, the centers of the side holes are 5/8" from the front of the rack ear, and are 5/8" from the top and bottom of the rack ear. Please see the attached image, which shows these dimensions. The side holes are used with #8 (U.S. size) or 4mm screws.

Also, please note that this is not a complete rack kit. Only the 2 rack ears are included in this listing. If you are rack mounting UREI gear you will also need 2 spacer washers or plates, along with 4 machine screws and washers. These parts can  be found in a separate listing on our ebay store..

These parts are not returnable so before buying, please be sure that the locations of the side holes are suitable for your application.
