Double ram mount

I’m looking for a ram mount that I can put two 5″ lowrance 520’s on. I’ve seen people with them before but can’t seem to find them on rams website. Any help would be great!

Here ya go: I think everything you need is here.

The ram that I saw had a large plate mounted to one ball. The two units then mounted onto the Plate. I don’t see that there.

I was thinking of the double ball set-up. I have used that in the past. Not familiar with what you are talking about. Sorry.

I will do some checking but do you think the person you saw it with custom made his by adding on more plate?

You think this is big enough?

The ones made for a 5″ are 6.25″ base.

I have looked at those plates but think they will be to short with the knobs that tighten the unit to the bracket. 13″ is what I née the plate to be

Then just get a piece of 1/4″ metal plate 13-14″ or however long you need and attach it to the ram base. Then drill holes to mount your graphs on it.
