I ordered the wrong size balances (S745-26 [25.25-4] and S745-32 [31.25-4]), the springs in the new balances are longer than the old ones and the cord might be too short when the balance is put in the window , see picture .
I may have used the wrong weight of the window when I chose them
I' d like to exchange them for the correct ones for windows weighing about 21 lb Before I did not see the numbers on the old balances The numbers are 3650 or 3680 for the six 26-1/4 and number 3872 for the 2 32-1/4 I had ordered
How do I return the wrong balances and order the correct balances?
Thank you
Lilian
