Think this one belongs to some older USA made box as it is very heavily made (2lbs+) size is 1.5" deep x 12.75 x 8.625 not much usage, very clean-red PJ and flanges on each end to fitment into the box--NO part # or I.D.. Maybe someone out there has one or knows what name box it was from? Thanks and LMK if you have info.……….Thanks...…...Cranky 8)
