Gonna plug a product that we use Cable Munkey talked with the manufacture of these and the 24lb rating is with a 5/1 ratio built in. They are rated and able to be hung in any orientation using a zip tie or tie line to cinch up the mounting hook. That said on our standard schedule 40 2 inch pipe they fit snugly enough that if you just have a few cables hanging they aren't moving.
I like the neatness and organization. I'm not certain about turning curtain track hangers into cable raceways. I'm especially uncertain that the batten is grounded to the venue grounding electrode system. One of those wires, with a pinch or simple wear, could energize the entire pipe and possibly the grid and other metal connected to the fly system. This is an advantage to plastic hangers - a cable insulation failure won't energize the truss or batten.like the cable itself! In a fire the cable is going to melt too.
Here’s an interesting way of cable managment.
My understanding is that they are growing in popularity but then also conversely have their own issues in that introducing water to a lot of electrical and softgoods which causes shifts in weight making linsets more dangerous to be around, is inherently problematic as well. I've also heard of at least 2 triggering by accident causing a ton of damage and necessitating large renovations to repair. I suspect those reasons they aren't more prevalent.Tbh I'm surprised deluge curtains aren't more common
I suspect this is the difference between firefighting concerns in the UK vs USA, as a generalization. I'm not a firefighter so can't speak to individual practices, but for the most part the inclination in the USA is to fight fires from the exterior of a large building unless there is reason to think humans may be inside.I just wondered about fire performance as in another place we had a discussion about just this problem, where in a fire the cables fall and even though the insulation may melt the cores are still there, and they are a hazard to firefighters, especially where cables have been slung over an entrance or gangway. Cable drop had to be in the RA and mitigation in place to avoid cables drooping over gangways and especially doorways.
If, as per your website, you show up in Houston for USITT2020 August 1-4, you'll be a tad late.Cable Munkey will be at USITT if you want to check them out more.
