I received the carriage I ordered in about a week which is when it was expected to arrive. The carriage I received was identical to the OEM carriage and fit on my garage door opener perfectly. It was a "piece of cake" to swap out the old carriage with the new one, it took about 15 minutes to do, a lot easier, and cheaper than changing out the entire garage door opener. I highly recommend this part if you have a Genie screw drive garage door opener.
