S600 Spiral balance

A home owner from Kew Gardens says:
I bought some S600 Spiral balances and am looking to buy some more. Who knew the top and bottom windows would be different sizes.
Do you have this black foam piece that holds the spiral in the track? If not can you suggest a substitute item. Thanks.

Hello,

Take a look at our 26-139 hole aligner and see how the dimensions compare to yours. Thanks for posting!
