Difference between 15-001 and 15-002?

Thanks for posting. The 15-001 has a width of 1-1/8", while the 15-002 has a width of only 1". While this difference may not seem like much, it is, in fact, vital to the operation of your balance. We recommend that customers get as exact a measurement as they can before ordering their balances.

As for the clips on the metal sash, can you please upload a few pictures? If we can see them, we can identify them and help find a way to remove them.

Please take a look at our 18-062, top sash guide. Do you think this might work for you?

Yes, there should be a thin metal take out clip that you pop out in order to remove the sash. It should look something like our 16-002 take-out clip. Please refer to our tutorial video on how to replace your non-tilt channel balances for further information.
