I used to use 4 of those with that same branding, Simmverter, on my first Pentium system.

There were 4 variations of the ones I had, for each combination of Tall/Short and Forward/Backward. This way, 4 such adapters could be nestled together in a single set of 4 72-pin sockets without physical interference.

Each one accepted 4 30-pin SIMMs, for a total of 16 per 4-slot system.

It was not amusing trying to get all 16 SIMMs to work correctly at the same time, but it was inexpensive to get spares and I eventually got better at being deterministic about which module to swap out to attempt to improve reliability.

(Things got a lot better when sticks of 72-pin EDO became cheaper.)
