Window balance

Question

I'm in of two 28" balances. Photos are of the original that have no #'s. I had replaced with 2740 years ago and just failed. The 2740 required a lot more effort to pull down so I the springs must've been too strong.
Searching your product line I think I need 28" from your 380 Series, likely the 2730. Would you agree?

Hello there!

Based on these photos, you could have the S380-28 or the S385-28. The Series 380 has a 1" deep shoe and the Series 385 has a 1-3/32" deep shoe. You'll have to measure as shown below to determine the best match.

We also recommend you weigh the window sash on a scale to determine the proper stamp option. There's a chart under the product description on the S380-28 and S385-28 store pages that you can use as a reference.
