Supers and Hive Bodies are available in select and commercial grades.
Commercial woodenware is the most common grade. It is equal in function and service to select. The difference is in the appearance. Large knots and minor blemishes are permitted.
Select woodenware is the highest quality clear wood available. It is free of blemishes and only the smallest of knots are allowed. If you want woodenware that is a pleasure to look at this is the grade for you.
