Perfect. Some thermostats require a C wire though not all furnaces have one or in my case none was ever run up from the basement. This adapter is sturdy, cheap, long as heck, and perfect to run your thermostat and you won't need to replace batteries anymore. I use it for my Wi-Fi smart thermostat which had no battery option at all.
