Milgard Vinyl window balancer

A home owner from Northern California says:
29 4 GV CMC 7 is imprinted on the window balancer. What is the weight of the balancer I should pick for the S350-29 series? And is this the right series for my window balancer replacement, thanks.

Thanks for posting. A stamp of "29 4" usually corresponds to our 2940 option. I cannot confirm what Series you have. I can say that many Milgard windows have been known to use our Series 385 in the past. I highly recommend carefully comparing the nylon attachments that come with both the Series 350 and Series 385 with your own hardware to confirm the better match.
