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.
Designation candidates
“NJ1011” across 2 loaded brands
One highest-ranked designation candidate is shown per manufacturer. Use Custom Compare when you want to choose exact suffix variants yourself.
