Steel Work Light Battern Hanging Clips

[SKY]

Have a job to do soon on my site to hange 8 light batterns in a boiler house from the steel guirders that form the roof.

What are these clips called that will bite into the side of the guirder so that I can hang chain down to my light batterns?

Thanks as always chaps

the guirders are called perlings you can use perling clips with lengths of stud iron

I've always called them caddy clips but I think that is based on a brand name
