Tony, if yours is like ours, the cord goes through a hawse pipe as in http://www.glendinningprods.com/cablemaster.html. Our male plug was damaged and we used an extension cord for a year. We worked our way to Conway, SC and Glendinning molded on a new plug end without removing the cable from the cabinet. I think Paul Horner had Liberty disassemble his cord cabinet and replace the cord.

If your install is like mine, I'd sure like to know of a plug that fits. I looked and could never find one.
