EFCO single hung window balance

Question

27" is the length of the metal Chanel. It is stamped with 2630. If you need better photos I'll have to remove it again for more info. Thanks

Thanks for your post! This window balance can be replaced with either the S351-27 or the S390-27. You'll need to remove the balance and measure the shoe to determine which of these two is the correct replacement.

Our 2630 stamp option will support a sash weighing 13 to 19lbs.

Comparison of the S351 and S390 balance shoes.
