The importance of nail placement

I am writing this letter in response to "A joint effort," March issue, page 24.

I must say, I am disappointed in the statements made in this article. In it, NRCA's Associate Executive Director of Technical Services Mark S. Graham states: "NRCA believes too much emphasis is sometimes placed on manufacturers' exact fastener placement locations."

I would like to know who at NRCA made that statement. It is just wrong. Nail placement is important.
