We're looking to replace a few window channels that do not hold our windows up anymore. The channels are stamped with "26 4 GW CMC 11". And the windows seem to be manufactured by Milard. Thank you for your help!

Thanks for posting! This window balance is similar to a few we stock. To narrow down the correct replacement, I'll need to see a photo of the spring and pulley system on the other side of the channel.

Please feel free to reach out with any other questions you might have!

Thanks for the requested photo! Your window balances can be replaced with the S378-27, S380-27, or the S385-27. You'll need to measure the depth of the shoe to determine your series.

A 2640 stamp option will support a sash weighing 19 to 24lbs. This is likely to be what you need but you may want to double check the sash weight.

Comparison of the S378, S380 and S385 balance shoes.
