The plate fits the 250-CO-PLT perfectly. The shame is that GE forced me to buy them to replace the carbon monoxide detectors in my house. When they "updated" the original, they changed the format, which changed the way the device was mounted and required special wiring to get the terminating resistor in the circuit correctly. The only problem was that I had to cut traces in the plastic to wire up the load resistor. Make sure you are willing to do some simple soldering and wiring for a proper installation.
