I have tested the LEMs with moving the wire around the inside of the window, and it was within 1% (at least with a LEM Hass 50-s with 3 wraps through the window, to cause it to behave like a LEM Hass 16.66666666-s). So, it couldn't hurt, but wouldn't be critical I don't think.
Crap, I thought I sent 5 of those cable glands.
I'm sorry about that. As a side note, it's possible they should have gone over the cable before adding the lug. But the gland thing may still fit over it.
