Basic Part Number Identifies the straight length, fitting, or accessory.
System Number (Straight Section Only) The first four digits make up the system number which identifies the structural, dimensional, and material characteristics of the straight length. It is made up of the side rail digits indicating the side rail thickness and flange width, the load depth (inside, in inches), and material finish (galvanized, aluminum or coated).
Secondary Dimension Number Identifies the length of a straight section in feet, the radius of a fitting in inches, or the second width of a reducer in inches.
Bottom Type Identifies the type bottom:
Prefix Number (Fittings Only) Fittings are ordered using the 3-digit prefix number given in the charts on the fitting pages. Fittings do not have stiffened upper flanges.
