Ribbed Inner Section Igniter Disc

Igniter™ MHS ribbed & v-grooved inner disk. Used to hold Igniter™ inside the smaller ribbed and v-grooved sections at MHS. These have a different hole spacing and do not directly mate to the MHS disks; use the adapter to step down to this sizing. The large hole at the bottom accomadates 4-40 threaded rod, while the smaller holes work well with the solid brass 1/16” rod (sold at most hardware stores in the US).
