(2) Lumber shall be six feet and longer and be in two-foot length increments unless the purchase agreement specifically stipulates different lengths.

(3) Lumber should have clean, sound ends but it does not have to be double-end-trimmed to precise length. If not double-end-trimmed, there should be sufficient overlength to allow square end-trimming the lumber to its nominal length.
