37" chanel balance

Thanks for reaching out! Your balances look a like our S380-37 with a 1" shoe or our S385-37 with a 1-3/32" shoe.

To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. If it is 7/8", please let me know; it will need to be a custom assembly.

Comparison of the S380 and S385 balance shoes.

Once you've confirmed the series, you'll need to select a stamp option for your balance. Unfortunately, I am unable to cross-reference the 3635 stamp from your balance with ours. That said, to confirm the right stamp, you'll need to obtain the exact weight of your sash.

There is a chart that lists the weight ranges each stamp option can hold to support the weight of a sash.
