What is Sidewall Select ?
It is actually a blend of grade Extra "A", which has no imperfection, and Clear "B", which has no imperfection on the exposed surface (up to 6"). Once installed, you will not see the difference.
Sawyers sometimes need to edge the shingle to get these grades (Extra and Clear). As a result, we obtain 2 shingles and 2 different grades from one piece of wood. But for Sidewall Select, edging is not necessary. You get Extra and Clear in one shingle, and therefore, wider shingles.
