replacement block and tackle balances and maybe mounts

Question

Hello!

I am hoping to replace the block and tackle hardware for a sash window that looks like it hasn't worked right in a long time. One of the block and tackle balances is missing in fact. and the mounts in the window frame look painted over.

The one balance I do have measures 22 inches for the channel. the markings are included in the photos, "21 5 26# AK CALDWELL"

I have more photos than this form will allow me to upload. If you have a place I can put them, I'm happy to send them along.

Please let me know if you require anything further.

Thank you for your help!

Hi, Marcos.

Your balance looks like either our S380-22 or S385-22, depending on the depth of the bottom fitting. The Series 380 has a 1" deep fitting and the Series 385 has a 1-3/32" deep fitting. Measure as shown in the image below to determine the best match. You will also need the 2150 strength option, based on your 21 5 stamp.
