Thanks for posting! I see that one of the stamps you have on the balance box is 7P27. I think you should look at our 24-737, which can be used to replace balance boxes with the stamp 7 27.

We received them and they don't look the same. The mounting holes of the old balance go right through the body (the center) of the old balance but the new ones dont have that. Can you please advise.

Thanks

Please take a look at our tutorial video on how to install an Andersen sash balance. This may help shed some light on how best to install your new replacement.
