Automatic candidate selection
One base designation across loaded brands
Exact designations rank first. Dimensions, suffixes and other technical differences remain visible so the result is not mistaken for an interchangeability declaration.
Dimensions differ
“322” across 4 loaded brands
The base designation is shared, but the loaded boundary dimensions do not agree. Use Custom Compare when you want to choose exact suffix variants yourself.
