Window slides

Question

Hello, I need to order 4 of these exact slides to replace mine.
All of them are the exact same.
The seem to say 27 2 LO Caldwell stamped on each of them. The metal part is 1/2 wide by 28 inches long.
I'd also like to replace the stops on the window. I don't see a part number for that but have included a picture.

Please advise on where to get parts to replace.

Hello,

It looks like you have either our S351-28, with a 15-002 bottom attachment, or S390-28, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2720 spring strength option for your replacement balances.

As for the top sash guide, it's hard to tell what you might need without seeing it uninstalled with detailed dimensions. That being said, you can start by comparing the specification of our 18-009 and 18-018 to yours. Thank you!
