Check the listing for details. Honeywell UDC3300 Universal Digital Limit Controller All Units In Working Order. Condition: Used. Listed at 229.00 USD. These Honeywell UDC3300 Units have all been power tested and came from a fully operational system. Some Units have slightly different model numbers so if you want a specific unit, let me know. I've numbered each unit in the pictures. As each unit sells, I will remove pictures of that unit so if you see the picture, that unit is available. They each come with 2 mounting brackets (check last picture) There is a next day air option available. If you choose this option before 3pm Monday-Thursday, the package will be in UPS possession that day and should reach you the next day assuming you are in the mainland US. If you need Saturday delivery, there will be an additional cost. Please contact me before purchase if you need next day air for Saturday delivery
