Does "Booth 6X2416" mean anything to anyone?

So, I just finished watching Eraserhead, and then I watched the extra feature, an eighty some minute interview with Lynch about making the movie. At the end of the extra, he says, "I've never heard an interpretation of the movie that matches my own." It then immediately fades to a washed out photo of the woman in the radiator. If you click on her right eye, it goes to a loop of Henry pointing to the words "Booth 6x2416" down the side of the screen. The font suggests a separation: 6 x 2416; but I'm not certain about that. Googling comes up with nothing. Any ideas?
