Kiln dried stocks of 26mm, 32mm, 38mm, 51mm, 63mm, and 76mm with lengths generally 2m - 3 m.

Distribution Black walnut is widely distributed throughout North America from south Ontario southward to Texas, and in the east from Maine to Florida, but it is not plentiful, firstly because its growth is scattered, and secondly, because of the clearing of ground for cultivation and the demands for the timber have exhausted the supply in many areas.
