content: This insert is too wide to fit into a Keystone plate; it is more properly called a QuickPort insert. Also, the so-called "RJ-11/RJ-12" connector has 8 wires instead of 4 or 6. It looks more like an RJ-45 connector. And, guess what, it does not fit a telephone modular jack (RJ-11).As you might guess, it got returned.
