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

“6800” across 5 loaded brands

One highest-ranked designation candidate is shown per manufacturer. Use Custom Compare when you want to choose exact suffix variants yourself.
