GN2370 Stainless Steel-Spacer plates
Chamfers, different sheet metal thicknesses, or seals could mean that the mounting surfaces of hinges to frame and door are not on the same level.
Stainless Steel-Spacer plates GN 2370, as accessories of the GN 237 family of hinges, are designed dimensionally so that they ensure the appropriate height compensation during mounting by shimming, either individually or in combination.
The 2nd table includes a number of potential compensation heights which can be accomplished by shimming with one or two spacer plates.
