Awning for height 230cm

drongo

Hello.  Does anyone know of any porch awnings that will fit awning rail height of 230cm. Up to now all the porch awnings that we look at start at 235cm so,  as we are not too happy at having to place the van on blocks we are struggling to find a porch awning
that is approx 340cm wide and 230 high.  Any ideas?  Thanks.
