SWISCO - The Replacement Hardware Authority

29-6 GA2 CMC 5 ??

A quick learner from St. Augustine, FL says:
I am replacing the channel balances on a non-tilt window for a customer. I have determined that I need the Series 380. The channel balance is 30 inches long. The channel balance has a code stamped on it 29-6 GA2 CMC 5. Can I determine the weight of the window with this number or do I need to make another trip to weigh the sash?

Typically, a stamp of 29-6 corresponds to our 2960 option, but it's always a good idea to weigh the sash just in case.
