MFJ makes the following products:

MFJ-4600, 4602, 4603, and 4605 Window Feedthrough Panel.

I have never used them so cannot recommend. Good luck in your quest.

I am hoping that someone(s) can give me some advice on cable window
entries.  I am looking for something like a 1/4" thick aluminum strip
to go in the window track.  The tracks are 38.5 inches apart. I was
unable to find a 4 inch wide aluminum flat bar strip at a reasonable
price ($40 for the strip and $40 for shipping).  I did find a 3 inch
wide strip and do have that. What I want to know is what length I need
to cut it to.  If I make it the full 38.5 inches long then how do I
get it into the tracks since I can't slide it in from the end?  If I
cut it to say 38 inches then what do I use to fill the other 1/2 inch
(or 1/4 inch on each end)?  Do I just use stick on weather stripping?

The second part is, how do I make the D shaped holes for the SO239
bulkhead feedthroughs or the UG492 BNC bulkhead feedthroughs?  I am
sure my 5/8" Greelee punches will not even make a dent in the strip. 
I do not have access to a vertical mill to cut the holes.

Thank you for your help.
