Good one, RickWish had know about this before , as it’s going to make things much more flexible.
I wanted to have my power for my work station and table saw drop from the ceiling .
My electrician used twist lock connectors, and I was going to use the 6” DC pipe as something to secure it to in order to take the weight off the plug .
Little did I know about these , although we used a version of them to pull cable .
Now they have a version that you use to hold the power cord up .
And it gives me more versatility,as I can mount a hook wherever I want on the ceiling if I want to change where I want it to drop , making getting the outlets in the perfect location less critical .
Here’s a pic . The second pic is of this system . The third is what we used to use back in the day for pulling cable . It’s a genius idea for hanging cords , as they do not slip
