Well said. Yeah after so many it becomes more of a feel then sight. I use to be able to do them in the dark , what do I mean by this? Well crawl under 1000s of these cubical/modular workstations/desk to terminate and you will know what I mean, haha. Running cable through these can be a pain in the b.... too, keep in mind they are usually already crowded with Electrical wiring and most of those bottom panels are a pain to work with, that is get them back popped on right...Oh and add the service poles you have to run your cable down from a dropped ceiling to each group of cubicles, those were the fun daysSome seem to like them. To me it's just another little unnecessary piece to keep track of and you have to look to see which way it's turned, feed things through the tiny holes in the insert, etc. By the time that I fiddle with and look at it that much I could be done with the others.
The key with all of them really is to get your wires laid out well. Straight, aligned, right length, with good clean square cuts. Once you do it enough you get the technique down and they'll slip right into whatever. If your cuts are kind of knuckled under and/or to the side and/or wires still kinked from the twist and/or laid over then much harder to get right going in,
