When you set out a stage set up, no matter how carefully you lay the delicate dmx cables (and I never use gaffa tape on cables), there is always someone who manages to find a way to accidentally step on them and damage them.
Running cables overhead is also a problem because of sagging and aesthetically they don't look right and obstruct someone's view.
I needed something so I could run several cables safely across the floor, and this is it.
The channels are about 30mm square and there are 2 in each, so you can comfortably run 6 or 8 cables through it without a problem. You can also use 1 channel for dmx signal screened cable, and another one for mains voltage power to prevent any interference. At 1 mtr length each and the fact that they interlock, they are a good product. I got them when they were on offer so very good price.
These are pretty robust and can withstand 11,000 lbs, although I am not expecting a vehicle to drive over them, personnel and wheelchairs have no problem.
The yellow flip over covers are not cleanly cut and you can see the quality isn't great, but for the price and the intended purpose, these are just right and because I was so impressed I bought three sets of 3 in all, so I have a 4 mtr walk over on both sides of the
