split cable gland to accept 3 cables

[KDA]

I need to replace the cable gland on my trawler
I need a vertical entry, rebuilt or "split" cable gland that will accept 3 cables (3/4", 3/8", and 1/4")
I have tried SeaView and Blue Sea but so far they can't supply what I need.
Any ideas from the brain trust out there?

Do you have a photo of what you want to replace?
