The reverse side of the cuttings in both FAS and Cabinet Grade are not required to be sound. No piece shall be admitted which contains pith, boxed or showing, exceeding in the aggregate in inches in length twice the surface measure in feet. Wane on the Cabinet side shall not exceed one-fourth the width by three-fourths the length in the aggregate, or pieces may alternately have wane one-third the width by one-half the length in the aggregate. Width of the wane may be divided and show on both edges. Length of wane allowed both edges. There is no 1st Lineal Foot Rule or restriction to knot size outside the cutting area.

There is no limit to the number of cuttings. Small knots or their equivalent, not exceeding ¼” in their greatest dimension, sound or containing unsound centers not over 1/8” in diameter, shall be admitted in the cuttings.

10. COM SHOP MINIMUM YIELD IS 50% OR 6/12 MINIMUM CUTTING SIZES ARE 3”X 2’ (CLEAR 1 FACE CUTTINGS – REVERSE FACE SOUND) 3.5”X3.6’ = 12 C.U. 5”X2’ = 10 C.U.

Minimum Size Cutting: 4” wide by 2’ long except that each piece must contain at least one cutting 4” wide by 6’ long. There is no limit to the number of cuttings. Wane shall not exceed one-fourth the width or one-half the length of the piece. Width of wane may be divided and shown on both edges. Length of wane allowed both edges. The cuttings will admit stain, season checks, slight surface shake, bark pockets, firm tight pith, worm holes, and sound knots that do not exceed in their greatest dimension one-half the width of the cutting. Other holes and unsound knots that do not exceed in their greatest dimension 1 ½” in 4” to 5” wide cuttings and 2” in 6” and wider cuttings are admitted. Other defects are admitted if they do not impair the strength of the cuttings.
