(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.
