Milenco M16 Wheel clamp

Milenco on Xmas break so can't phone and ask them   Hoping someone on here might just have insight.

Looking at wheel clamps for our MH, Renault Master base. 225 16 wheels. Have (sadly) discounted Bulldog's EM4x4SS as I don't believe the bar will go through the wheel trim. Instead was close to ordering the Milenco M16. However, although it doesn't say so on Milenco's own website, on retailer's websites it is described as "Ducato/Boxer only". I can't figure out why it would be specific to type rather than wheel size. Anyone have experience of this clamp on something other than those ? 

Much appreciate any help.
