3/4” Rommex Connectors

I’m a homeowner that is trying to save as many knockouts as possible on my new 66 space load center breaker panel. I’m looking for 3/4” (knockout) rommex connectors that are listed for more than two 12/2 NM cables. Would love if they are ones that homedepot, lowes, or menards carries.

Let me know if you had experience with them and would recommend. I found 2 from Arlington. Metal one is expensive and plastic one haven’t seen if anyone has experience with it and recommends it.
