415 2 Aluminum Extrusion JIS Standards Unit: mm Note t Given values are for extrusions placed on flat surfaces with minimized bends by own weight. t When the overall length is not an integral multiple of 300mm, determine the tolerance by rounding up the remainder length to 300mm. Bending L Bending Note Not Applicable to the plane including open section.
