Stainless Steel Decorative Wire Mould ???

Is there a source for stainless steel wire moulding with a matching single gang box or similar? I need it for a access control reader installation.&nbsp; Alternate ideas appreciated, Wall penetration is not an option (poured concrete with rebar)/elevator shaft.
