This part does not show that it works on an Invacare brand bed, as it was made for Drive Medical brand hospital beds. Since we are a dealer for Invacare, we can find part information with the Serial Number for that hospital bed. On an Invacare unit, it should be found on the back or bottom of the frame. It will start with 2 digits corresponding to the year of manufacture, followed by a letter that would represent the month, (A for January, B for February and so on) followed by 5-7 digits.
