This adapter is designed to securely fit into a Lucent M1000 MultiMAX Patch Panel. This will also apparently work on a CommScope M1000P5 MultiMAX patch panel, however I don't have a CommScope patch panel to test with. I have tested this keystone adapter with CAT6 Keystone Jacks (P/N TC-K25C6BK)

Prints in the included photos were printed on a stock Flashforge Creator Pro using blue Polymaker ASA filament.

I've tested adding/removing these adapters to my panels about a dozen times and have not noticed any loss of holding power - however your mileage may vary. For durability I recommend leaving these adapters in place once installed since I did not design this adapter with frequent removal in mind!
