REDWOOD GRADES & TERMS:
Comparable to a high-end Heart Bee. This redwood grade permits two knots up to 1-1/2″ diameter on a 6″ wide piece for lengths to 14 feet, and three knots for 16-20′ lengths. For lumber 4″ and thicker, Super Select may allow more knots, all must be tight and sound. Edge sapwood may be present in some pieces.
Free from knots on all faces, no sapwood. Any defects are limited to the reverse face. CAH is the highest quality of the redwood lumber grades available (aside from dense vertical grain), and is without peer for exterior construction.
