These four pictures show the finished feed through, although I really should call it a "pass through."

The second photo shows how the "stopper" on each end works. The originals I saw at the test range were 6" across and has a big "X" cut in the rubber ends. You could easily push your cable (and your hand) through there. But with a 2" OD pipe it's more difficult to manage, so I cut a "C" shape into the ends and installed a knob to open and close the end caps.

The third photo shows the pass through in place in the floor. The hole under the outlet lets the cables run into the cabinet without the need for the door to be left open.

The last photo shows the outside view underneath the trailer.
