This balance looks like a S770-30, with a stamp option of 30C. Just make sure your old balance attaches to the top of the window track via a screw; sometimes we see these balances using a hook instead, in which case it would have to be custom made for you. For the wool pile, we need the exact size of the base and the height of the pile. These dimensions can be very specific, often going into the X/32" range, so be as precise as possible. If you need to replace the pivot shoe as well, we'll need to see it out of the window and you'll need to tell us the exact width and thickness of the shoe. From there, we should be able to help you. |

Thanks for bearing with me during this busy time of the year. For your wool pile, take a look at the 58-127. This has the dimensions you listed, but if you want to be safe, you can order a sample to try out from our samples page here. Samples are free; only shipping charges apply. Thanks for confirming that this balance attaches with S-Clips, like our 19-029 or 19-030. We can install rivets at the top of these balances that the bottom of those clips hook around, while the top of them attach to the hole in the window track. I'm afraid I need just two more pieces of information to get this started: C
Finally, I shouldn't neglect to again mention that if you need to replace the pivot shoes at the bottom of the window tracks, please show us one out of the window along with the width and depth of the shoe. Thanks again for bearing with me we're almost there. |

Thanks for getting back to me with all this information. This confirms to me that you need the rivet in the second-to-top hole. If your window sash weighs. 25.6 lbs, with little margin for error, then I think a stamp option of 30D is the right way to go (for a sash in the weight range of 24 through 29 lbs). I am glad we checked this! I am emailing you right now a custom link to order (4) 30" Series 770 balances, stamped 30D, with a rivet installed in the second-to-top hole. You can reuse your old S-Clips, or buy the 19-029 or 19-030 separately. Let me know if you have any other questions. |
