I'm with Dave on this one.
And don't worry about blocking for the ends. I'd say; as long as your rail brackets are within 8-12 inches of the ends, this will eliminate any flexibility at that point. Just cut a 45 degree angle on the ends of your rail, temporarily mount the rail to where is sits solid, then measure from the "long point" of the angle to the wall and this will guarantee a tight fit for the end pieces. Add glue to the joint, pre-drill 2-1/8" holes at the correct locations so that the 2-1/2' GRK star tip finish screws
will secure the end pieces properly and be long enough to grab. Fill the holes with matching putty.
I find that these type "wall anchors
" work well where there is no stud to mount the rail brackets.
