How to Measure

To accurately specify rectangular tubing, always provide three key dimensions in order: Outside Width (the longer flat side), Outside Height (the shorter flat side), and Wall Thickness. All dimensions are typically in inches. For example, a tube measuring 2 inches across one flat side, 3 inches across the adjacent side, with a 0.125 inch wall is noted as 2 x 3 x 0.125 rectangular tubing. Use calipers for precise measurement. Measure the outside dimensions across the flats, not the corners. For wall thickness, a micrometer is best; if not available, measure from the end of a cut piece. When ordering from Bobco Metals in Los Angeles, specify material, these three dimensions, and your required length for an accurate quote.
