Yes, this is the complete unit – the “flag” spring and holder that slides onto the end of the feed trays is installed – this is a used item, may have a few scratches and scuffs but will be usable. If you know = you know as they say. Only one place to get them….. Now you can get them here for almost half price!! Great to have at least one in stock, when you need it then you need it. I have seen people take off the feed trays and drop them around here and there and break them many times. NOTE – I have all parts for the tabletop folder inserters. Send me a message to inquire about parts, service issues (I can diagnose most issues with a video/text) and I do offer a rebuild service for your machine – along with complete machines. Feel free to make an HONEST offer – This is a great unit and this is your chance to get it at an even better price! This unit works great. I have a myriad of references and I will make them available if requested. Please feel free to ask questions..
