Hello G Man,
Thank you for your question regarding the Delta Adjustable Slide Bar / Grab Bar Assembly and I am happy to assist you today.
Unfortunately at this time, we do not have an 18" ADA grab bar which matches model 56302, although our sister company, Liberty Hardware manufactures an ADA grab bar which will match. The model number associated with the bar is DF5918-PC.
I hope this is helpful!
