Bushing or cord grip for 1/2" KO

[mcbane]

I need to run cat6 cable and a similar diameter 0-10 v dimmer cable into a number of steel junction boxes for a CA-approved lighting system. Can anyone recommend a bushing or cord grip to get the cord into the box at a 1/2" knock out?

Thus far I have found relatively cheap ($0.50 each) bushings that dont grip the cord well (https://rexel-cdn.com/Products/MorrisProducts/22348.pdf?i=54A702A5-D5BA-4E94-9B5E-B28B03FDD065). I have also found cable glands that grip cords very tightly but prices seem to start at $2 each.

thanks for any suggestions

I use Heyco cord grip/ strain relief/ liquidtites whatever you call them
I do pay about $2 each




That said these are very similar- though I have no experience with them

Does it have to be plastic?

I'm a low voltage contractor and we usually use Romex connectors. They're dirt cheap and have screw down clamps.

Not sure if metal clamp ok. Probably not UL listed for this purpose but the cord grips probably aren’t either. I’ll talk to inspector before proceeding.

its low voltage, no inspections required

They make rubber grommets that fit in a 1/2" KO for this. I dont know if they make a cord grip that will go that small for your cable. As already said, romex connectors will work also, I like the plastic ones mad by Dottie.

^ That would be my choice too, if permissible.

Even within the 1/2" KO size, they can usually be had with 2-3 different size rubber inserts to cover different cable sizes.
