I usually choke a 3ft+ sash cord on the cable pick and tie a shoelace know around beam or anchor point.
do you guys have a preferred knot to tie cable pick?

an interesting observation is you state a "rated carabiner or shackle" which begs me to ask the question is your prussik rated? I mean really rated in working load limit? did you tie your own prussik loop or is it a stitched loop. Then the carabiner is usually rated in MBS (mean breaking strain) so no the same as the rating on a shackle which most likely has a 4 or 5 times safety factor for lifting. Is everything in your system rated the same way (MBS or WLL). Of course the final factor will be is it safe? Of course it is. It will carry/hold the load. A 10mm natural fibre or synthetic rope has a Wll of 100kg but will most likely have a MBS of 400 to 500kg.
"Rated carabiner" simply to differentiate from the cheap ones that I wouldn't even trust to hold a poster.(the ones that hold my keys to my belt) Generally I would use a climbing 'biner with a locking gate.an interesting observation is you state a "rated carabiner or shackle" which begs me to ask the question is your prussik rated?

I a m sure you will agree it is food for thought.
Have a great (and safe) day

When doing theatrical picks, I'm a big fan of either two slings in a bridle, or two cloves with a bowline "between" them, to increase the bend radius, more so with data. I haven't decided if I'd rather have ropes to the pinrail or chain motors--it varies based on the last venue I was in, usually.The correct knot is generally whatever one you can tie one handed in your sleep. But since a cable pick can vary from a single Cat 6 cable dropped 12 feet to enough soca and feeder to snap a piece of 12" box truss (yes this happened on a TV show a year or two back) there's obviously no one answer. But personally for most "regular" picks I like 1"nylon slings and a biner or shackle. Super quick to choke or prussik and wide enough to be kind to the data cable. YMMV.
