Medium voltage cable supports

[Mike01]

is anyone familiar with cable supports (non-metallic) for meduim voltage cable within a pull box? I have a large pull box for a straight pull and need cable supports but cannot find any for this installation? would these have to be UL rated?

I agree. Use them all the time. Need to make sure that the cast-in channels match the spacing for the side rails.
