Help Indentifying This Bottom Shoe

Hello,

My window channel balance looks a lot like your Series 350 (S350-23) except that my bottom shoe (pictured) is much more angular than the photos of your 15-004 shoe indicate to me. In fact, I don't see any bottom shoes in your catalogue that appear to exactly match mine. Dimensionally, the two parts seem to match. I'm just concerned about what appears to look like "rounded corners" on your version. The balance is to a Weather Shield non-tilt double-hung wood window circa 1981-ish. Is your Series 350 an acceptable replacement? Thanks in advance for your reply.

Hello,

The shape of the shoe is not important. The depth of the attachment is what needs to match up for the balance to fit properly in the window channel. The 15-004 measures 1-3/32" deep. Measure yours to see if it's a match. Thank you!
