I need your help identifying this 30in channel.
There are no markings but there was a stamp.
Thanks for your time.

Start by looking at our Series 385 channel balance. This may be a good match. Keep in mind that this comes with our 19-005 top and 15-004 bottom, so as long as these match up you should be okay.
