Milgard Non-tilt Balancers-Stamped 26 4 FV CMC 7

Question

Need replacement for this balancer. I don't think they are the original Milgard balancers.
Metal channel is 27" long and the plastic ends are as in the photos.
The window sash weighs ~19 pounds.

Please advise.

Thanks.

Thanks for reaching out to us. It looks like you have either the Series 380 or Series 385 channel balances. You'll have to measure as shown below to determine which one is best for your repair. I also recommend the 2640 strength option based on your 26 4 stamp.
