Here are the hole dimensions for mounting a Leviton QuickPort Jack in a sheet metal plate:
.595” (+.010/-.005) x .772” (+.003/-.005)
Recommended sheet metal thickness is 16 gauge (.0598”). We allow .003 - .005 for powder coat on each side of the metal, so max recommended thickness is .0698”.
NOTE: This hole dimension is ONLY for mounting QuickPort jacks in a single-wall sheet metal panel or plate. This will not work to retain a QuickPort blank filler, a QuickPort F-Connector, etc. A jack mounted in this fashion will protrude beyond the front of the sheet metal approximately .375" (3/8").
