|Spacer plate: Stainless steel, European Standard No. 1.4301 (American Standard Series 304), matte finish
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.
GN 2370 spacer plates, as accessories of the GN 237, GN 337, and GN 437 family of hinges, are designed dimensionally so that they ensure the appropriate height compensation during mounting by shimming, either individually or in combination.
The second table includes a number of potential compensation heights which can be accomplished by shimming with one or two spacer plates.
