Zip style ties are a pain to remove without damaging the cable especially if you need the cable mounted tight. What we've done here is to zip tie a length of Velcro tape to the rack structure. Then you can add/remove cable when ever without having to cut ties and re string them, just unwrap and re-wrap the Velcro tape. It lasts a long time and if you have to you can still pull the cable through the Velcro with out using excessive force. You can also do the same thing with the pre-cut Velcro straps, the ones with the wider end so you can pass the Velcro through itself. take the end with the hole in it and slide it over the cable management fingers then wrap it around your cables. = fast and neat.
