I'm looking for a safety thimble to suit 11mm (~7/16") Dyneema rope, this one below is the style I'm looking for but it seems VIKING are no longer making these.

Factor 55 make these more expensive ones but appears to be only for 3/8" rope or smaller.

So far I have only found this one from MASTERPULL which is not quite what I'm after.

Does anyone known where to get a proper safety thimble for 11mm rope?
