Ion Trap Question

[maxm]

Well, I'm making progress on the Hallicrafters 601 12" set i'm working on, from the thread "Is this flyback dead".
I just put the CRT back in, and was about to put the ion trap back on, when I noticed an arrow on the trap. I made note of where it was on the neck, but not the direction, since I figured that it didn't matter.
Does it matter?
Is the arrow supposed to point towards the base or the screen?



Thanks, almost ready to try it out!!
