To expand on Leon's idea a bit, the object is to provide a
secure railing to a plastered wall with unknown stud locations.
Rather than use a 1x4, use a 1x8 oak board attached to the
wall with two rows of 1/4" molly boats on 8" centers.
The board provides the structure to mount the rail while also
spreading the rail load across a larger surface thus reducing
the load any specific molly carries.
