26 inch window balancer

Thanks for your post! This balance reminds me of either the S380-27 or S385-27. You'll need to measure the depth of the shoe to confirm the right series.

You'll need to select the 2630 stamp option. A pair of these will support a sash weighing 13 to 19lbs.

Comparison of the S378, S380 and S385 balance shoes.
