Application Examples
Part number 5176401 defines a part with drawing number 51764. The part number 5176401 potentially defines multiple finish variations when a suffix is added to the part number.
A part number of “5176401-AN01” means the part is to be clear anodized per Table 1.
A part number of “5176401-AN02” means the part is to be black anodized per Table 1.
The finish suffix can be applied to top level assembly part numbers. This defines the finish on all appropriate sub-component parts within the assembly.
A part number of “710390690-AN05” means the part is to be black hardcoated per Table 1.
