MMR diaphragms are used with SMR series top jaws which are bolted on from the rear of the diaphragm. This eliminates the possibility of having an interrupted clamping diameter since there are no counterbored mounting holes in the top jaws. MMR diaphragms are also available in 2, 3, and 8 jaw configurations.
