Thanks for writing in. This looks like a S377-30 to me. Your stamp code of I-29-3 likely conforms to our stamp option of 2930, which is for a window sash in the weight range of 16 through 23 lbs. If you are uncertain this is correct, weigh your window sash to be safe. Let us know if you have any other questions.
