Arca Swiss style plates and clamp cross reference
Many claim to be Arca Swiss compatible, but after looking at them in detail and testing, one can find this to be not always true.
The dovetail plates have slight width, height and slant variations that can lead to incompatible combinations.
In addition, some vendors have lever clamps that work only over a smaller width/height range than their knob based clamps. The table below covers only knob based clamps unless otherwise noted.
General dovetail shapes are used by other manufacturers as well, but with measurements pronouncedly more different so they are not in the table as they are not even meant to be Arca compatible.
