    I am trying to find a Banana Jack to "mount", for lack of a better word,
    on the end of a wire. All the banana jacks I can find at Mouser or
    DigiKey are all designed for panel mounting. Does anyone know where I
    can get one that will mount to the end of a wire, with a 10 to 15 amp
    rating, and insulated so there won't be any shorts? Also if it was a
    dual jack that would be great too

    The dual banana jacks and plugs used to be known
    as Pomona connectors, after the manufacturer.

    Hope this helps!

    I had the same problem - couldn't find any so used panel mounts with heat
    shrink on the panel end - looks crappy but does the job

    I did, and this was the blurb on hit #5:

    I'm kind of surprised that something like that didn't come up,
    but then again, when they were invented, they were for patch
    cords or something, weren't they?

    They're known in some parts (Europe?) as "4mm jacks" or "4mm sockets"

    If this must look professional and cost is no object;
    you might consider a "BNC to double binding post - dual banana"
    adaptor (Jameco 125233CH @ $4.95 with female BNC)
    and use a standard BNC cable end to connect to it.
    Rated at 500V, but no current rating given... 10-15 amp
    seems a bit excessive for BNC connectors, though.

    Back in the "good old days" equipment had lots of dual-banana
    connectors, especially 600-ohm audio stuff. The dual-female
    connectors like you seek were available, but not common.
    The BNC adaptors were expensive, so there were never a
    lot available either. The 0.5-assed approach was to use a
    standard "stacking" dual banana, which had male plugs
    and female receptacles on the same connector. The real
    intended use of these was to connect several lines to one
    set of output panel binding posts. But you could connect
    2 of these in-line, if you could deal with the exposed
    bananas dangling in space... for a quick test, we often used
    "creative cable draping"; for a longer (but still kludgey) setup
    there was always electrical tape around the bananas.

    Of course, all this was to avoid the hassle of doing the
    job properly and making a longer cable!

    Best regards,

    Get 3/16" brass tubing from the hobby shop. Take a plug with you to
    make sure it fits. Cut about an inch long. Solder or even crimp
    the wire at one end. Cover all with heat shrink tubing. Trim the
    heat shrink, letting it extend over the end by just a hair.
