* Tubing may have its sides failing to be 90° to each other by tolerance listed.
**Twist is measured by holding down the edge of one end of a square tube on a surface plate with the bottom side of the tube parallel to the surface plate and noting height that either corner on the opposite end of the bottom side is above the surface plate.
Convexity and concavity: Measured in the center of the flat side, tolerance is ±0,010 inch applied to the specific size determined at the corner.
Straightness tolerance:Permissible variation in straightness is 1/16” in 3 feet.
Telescoping: Using 12 gauge or 14 gauge square tube, consecutive size tubes shall be cleaned of galvanization burrs and shall telescope freely for ten feet.
Hole tolerance: Tolerance on hole size is ±1/64” on a 7/16” hole size. Tolerance on hole spacing is ± 1/8” in ten feet.
Packaging: standard seaworthy packing, bundle, container, etc
