I need a pair of balancers for my window.
I attached photos of the part as taken from two sides, as well as a picture of each of the ends.
The metal channel is 21 inches long.
Thank you for your help!

Thanks for your photos. Based on what I see here, you have either our S380-21 or S385-21, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Comparison of the S378, S380 and S385 balance shoes.

Thank you for your help.
My daughter measured the shoe at 1.0" depth, so I need the S380.
One more question, I cannot see a marking on the existing part for the Option of 2010 through 2050.
Are you able to determine the option from the pictures I included?
Mahalo,
Mark

Sure! Your old stamp of "20 3" is just an older version of our 2030 stamp option. You can always confirm by weighing your sash. Two balances with the 2030 stamp can hold 12 through 15 pounds, so as long as your sash weight falls in that range then you should be good to go.
