Channel replacement
Thanks for posting. This looks like either an S380-30 or S385-30. The only difference between these two channel balances is the depth of the bottom nylon shoe, or its measurement from 'heel' to 'toe'. See the illustration below for reference. Compare with your old balance to see what matches best.
Yes, to determine the stamp option, you'll need to obtain the exact weight of the sash these balances support, then match that exact weight with one of the weight ranges listed alongside each stamp option under the product description of either the S380-30 or S385-30 shop page. Let me know if you have any other questions.
Hello again! The stamp on your neighbor's balance translates to our stamp option of 2940, which designates a balance that can support a window sash in the weight range of 23 through 28 pounds. Now, if your neighbor's balances and window are completely identical to your own, then this might indeed be the correct replacement stamp option to go with. I would still weigh your sash though just to be safe. Even if the windows are the same size, if one is of a slightly different build compared to the other, it may be a different weight, and thus require a different stamp option.
Let me know if you have any other questions, and thanks for the kind words!
Thank you, and you as well!
Great! That looks like 30" to me, so I think you're on the right track.
