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.
Data incomplete
“BK1512” across 3 loaded brands
The base designation is shared, but too few brands have complete boundary dimensions. Use Custom Compare when you want to choose exact suffix variants yourself.
