18" long, 1/2" wide

Hello,

Your balances remind me of either our S380-18 with a 1" shoe or our S385-18 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. Keep in mind, there is a chance that the shoe depth could measure 7/8". If so, please let me know as these will need to be a custom assembly.

Comparison of the S378, S380 and S385 balance shoes.

Unfortunately, I am unable to cross-reference the stamp from your balance to the stamps on our balances. With that said, it would be best to obtain the exact weight of the sash to determine the best stamp for you balances.
