Standard Lu Ban Door Sizes (1 · 2 · 4 Leaves) & Mason Rough Wall Openings
When building rough brickwork, masons require the Rough Wall Opening (Clear Opening plus 2x side jamb thickness for width and 1x top header thickness for height) so that once the 4.5 cm or 6.0 cm wooden frame is installed, the final Clear Opening lands squarely in an auspicious Red Palace.
