Hey Louis. This looks either the 39-253RB or 39-439B dual arm operators. The difference between these two operators is in the appendage at the end of the straight arm; the video below explains more. In either case, for a new cover and handle, see either our 39-376 or 39-452 , depending on the style you prefer. Also see if you need to replace the track: either our 39-566 or 39-528 , depending on your setup. Let me know if you have further questions. |
