Figure 5: NO.4 CLEAR (Export Export R-List Rules) is recommended and widely used internationally as a multi-purpose remanufacturing product. Each piece is well manufactured. Irregularities on reverse face can be slightly in excess of those allowed on the face. 

Figure 6: 6/4 RWL NO.1 SHOP (WWPA Rules) reflects the grading principles behind typical U.S. factory-type timber. This grade will yield from 50% to 70% of No.1 Door Cuttings, except that pieces containing one or more NO.1 Door Cuttings will permit one No.2 Stile. Not over two Muntins are included in any piece. The intended recovery of standard-sized pieces, which influences, along with allowable characteristics, the assigned grade, is indicated by lines on the photograph.
