Request verification for correct balance

Handy Person from Jacksonville OR
This balance is 27" long measuring metal only. The bottom attachment (15-004) measures 1 3/32" (Series 385?) The top is the 19-005. The window weighs in at 21.2 pounds. My assuption is the existing balances were slightly oversized to lift more easily. Is that correct? This is a non-tilting window. Channel measures slightly over 1/2"in width.

Thanks for your help.

Thanks for writing in! It does appear that the S385-27 may be the correct replacement for your balances, but there is just one more detail I'll need to see to confirm. May I please see a photo of the center of the balance where the string and pulley meet the spring?

Are you meaning slightly over-sized in regard to the length? If so, the length of the balance and stamp typically are not the same. In most cases, the stamp is one number below the length of the channel. We use that to determine the weight range the balances should be able to hold to support the weight of the sash.

I'm not referring to length. I'm referring to the balances ability to lift the window more easily by using a stronger balance (next weight range). Is this possible or would it interfere with the ability to close the window (making it harder to close).

Thanks for the fast response.

Thanks for clarifying. The 26-4 stamp on the balance denotes that the balance can support a sash weighing 19 to 26lbs. That said, the weight range of the balance is exactly what it would need to be to support the weight of the sash.

Given the metal bracket and the blue, nylon bracket, this balance will need to be a custom made assembly. To confirm pricing and availability, I will need to know the exact number of balances you intend to purchase. there is an order minimum of (2) balances for a custom assembly.
