Load Depth
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 (aluminum, galvanized, hot dipped, or stainless steel). 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. Width – Identifies the inside width of the tray in inches. Basic Part Number – Identifies the straight length, fitting, or accessory.
