RJ45FF6PNL is a RJ45 chassis mount feed thru connector that offers several mounting variations. It can be mounted with the supplied metal escutcheon (pictured on the left). It can be mated with a version of Whirlwind's MDSPL for mounting in any standard rack panel or box that's been pre-punched for Whirlwind or Switchcraft D-Female holes (pictured on right, a Neutrik "D" size MDSPL plate is also available). Standard Whirlwind wall plates can be punched to accept this feed thru for direct mounting.
