For sale is a ITI Learn Mode Recessed Door Sensor Brown 60-409-11-319.5 New. These are old stock so new batteries may need to be soldered in (I have not checked). I will pack them carefully for shipping. I also have the white version available in a different listing. I have updated the quantity on these a few times, but I am finally at the end of my stock, once these sell I won't be getting any more. Thank you!
